“How long is this going to take?” It’s one of the most common questions I hear when a patient is starting IVF, usually from someone who is already mentally rearranging their work deadlines, a family wedding and a vacation they haven’t even booked yet. It’s a fair question. IVF isn’t one appointment: it’s a sequence of steps, from testing to shots to retrieval to transfer, and each step runs on its own clock.
TLDR? From your first injection, an IVF cycle with a fresh embryo transfer takes about 4 weeks to reach a pregnancy test. If your embryos are frozen and genetically tested first, which is now the more common path, plan on roughly 8 to 10 weeks. Testing and planning usually adds a few weeks before any of that.
I’m Dr. Lucky Sekhon, a double board-certified Reproductive Endocrinologist and Infertility specialist practicing in New York City. I spend my days guiding patients through IVF, and I’ve been on the other side of the exam table too: three attempts at freezing embryos taught me that knowing the medicine does not make the waiting any easier. Through Instagram and my book, The Lucky Egg: Understanding Your Fertility and How to Get Pregnant Now, my goal is to make fertility treatment feel less like a black box. In this post, I’ll walk through each phase of the IVF timeline, how long it usually takes, and where your schedule is most likely to change.
The IVF timeline from start to finish
There are really two answers, and which one applies to you depends on a decision you’ll make with your doctor about your embryos.
With a fresh embryo transfer, where the embryo is transferred in the same cycle as your retrieval, usually 3 to 5 days later, the stretch from your first stimulation injection to your pregnancy test is roughly 4 weeks.
With a freeze-all cycle, where embryos are frozen (and often genetically tested with PGT) and transferred in a later cycle, it’s more often 8 to 10 weeks from first injection to pregnancy test. That’s the more common path today: most transfers are now done as a frozen embryo transfer in a separate cycle, which leaves time for PGT results to come back and lets your body settle back to baseline after stimulation.
Then there’s the lead-in: fertility testing, treatment planning, insurance authorization if it applies, getting your medications delivered, and sometimes birth control pills to control the start date. In my experience, that planning phase usually adds another 2 to 6 weeks, but it varies a lot from patient to patient and clinic to clinic.
IVF timeline at a glance
| Phase | Typical length | What happens | Path |
|---|---|---|---|
| Testing and planning | ~2–6 weeks* | Workup, treatment protocol, sometimes birth control to time the start | Both |
| Ovarian stimulation | 8–12 days | Daily injections and monitoring every few days | Both |
| Trigger to retrieval | 34–36 hours | Trigger shot, followed by egg retrieval under sedation | Both |
| Fertilization and embryo growth | 5–7 days | Fertilization check, then embryo development to blastocyst | Both |
| Fresh embryo transfer | Day 3–5 after retrieval | Embryo is transferred during the same cycle | Fresh |
| PGT results | ~1.5–2 weeks* | Biopsied embryos stay frozen while results are processed | Frozen |
| Period after retrieval | ~2 weeks* | Hormones fall back toward baseline | Frozen |
| Frozen transfer prep | ~3–4 weeks* | Uterine lining is prepared for transfer | Frozen |
| Pregnancy test | 8–10 days after transfer* | Beta hCG blood test | Both |
*Typical ranges in my practice. Timing varies by clinic, lab and how your body responds.
Approximate total from first shot to pregnancy test: about 4 weeks for a fresh transfer, and 8–10 weeks for a freeze-all cycle with PGT followed by a frozen transfer.
The established pieces of this timeline come from the American Society for Reproductive Medicine: stimulation generally lasts 8 to 14 days, egg retrieval usually happens 34 to 36 hours after the trigger injection, and embryos can be transferred anywhere from one to six days after retrieval. The ranges marked with an asterisk reflect how IVF is typically scheduled in clinical practice, so they vary by clinic, by lab and by how your body responds.
If you’d rather watch than read, I cover why IVF is shorter than most people expect in about two minutes here:
Before you start: testing and planning
Before I prescribe a single injection, I want to understand what we’re treating.
That usually means bloodwork, including ovarian reserve testing; a transvaginal ultrasound to look at your ovaries and your baseline antral follicle count; an evaluation of the uterus when it’s indicated; and a semen analysis whenever sperm is part of the plan.
That last one sounds obvious, but you would be surprised how many second opinions I see from people who did treatment without one. Don’t skip the semen analysis on the assumption that IVF will solve whatever is going on. A complete workup shapes how your cycle is designed and how fertilization is approached in the lab.
Sometimes I also put patients on birth control pills before stimulation. No, we’re not treating infertility with birth control. The pill quiets the signals from your brain to your ovaries, which essentially freezes you at baseline, as if you’re on day three of your period indefinitely. That lets us pick the day your cycle starts, so it can work around the lab’s schedule and your own life: a work deadline, a wedding, a trip you already booked.
Ovarian stimulation: about 8 to 12 days of shots
The honest answer is: it depends (insert Sima Aunty side-to-side head wobble here). For most of my patients, ovarian stimulation means about 8 to 12 days of injections. ASRM describes a slightly broader range of 8 to 14 days, but 8 to 12 is what I most commonly tell patients to expect.
You’ll usually start on day 2 or 3 of your period, or after your last birth control pill if we used the pill to schedule things. I say this as someone who grew up with a deathly fear of needles (and bugs, but that’s another post) and has done multiple IVF cycles myself: the shots are rarely as bad as the dread.
Then comes monitoring: bloodwork and an ultrasound every few days so we can follow your hormone levels and watch your follicles grow. Most of my patients come in five or six times over the course of stimulation, usually early in the morning, so they can get to work afterward.
And this is where people get unnecessarily nervous.
I stare at follicles for a living, and I’m perfectly comfortable seeing very little growth at the first monitoring visit or two. Often the first sign that the ovaries are waking up is a rising estradiol level, not bigger follicles. The visible growth tends to come in a burst during the second half of stimulation.
That’s why comparing your day-five ultrasound to a stranger’s on Reddit is rarely helpful. Your doctor is watching the whole pattern: follicle sizes, how evenly they’re growing, your hormone levels, and how all of it is changing from visit to visit.
I go into much more detail in my guides to follicle growth during IVF, estradiol levels during treatment and IVF medications and protocols.
I often describe it to patients like this: your protocol is a starting plan, not a train timetable. It’s a dynamic dance between your biology and our strategy. We adjust your doses, and ultimately choose your trigger day, based on how you respond.
The trigger shot and egg retrieval
When enough of your follicles look ready to hold mature eggs, it’s time for the trigger shot.
In my practice, I’m usually making that call when the majority of follicles have reached somewhere around 14 to 18 mm or larger. Please don’t use that number to grade your own ultrasound, though. Your doctor is weighing the whole group of follicles, your hormone levels and your treatment plan, not one measurement.
Timing the trigger is everything. Too early, and the eggs may be immature. Too late, and you risk ovulating before we can retrieve them. We’re aiming for the Goldilocks moment: not too early, not too late, just right.
After that, the schedule is very precise. ASRM notes that egg retrieval usually happens 34 to 36 hours after the trigger injection. I tell patients: about 36 hours, or essentially two days after your last shot.
The retrieval itself is a short procedure done under sedation. Using ultrasound guidance, a thin needle passes through the vaginal wall into each follicle we can reach, and the fluid (and, hopefully, the egg inside it) is collected.
Afterward, expect to be sleepy from the anesthesia. Cramping and spotting are very normal for about a week. Most of my patients go back to work or school the next day, although if you had a very high number of eggs retrieved (more than 20), give yourself a little more time, because the bloating and cramping can be more intense.
Your ovaries stay enlarged for a while, so I ask patients to avoid anything high impact for about two weeks after retrieval, or until their period arrives. My guide to exercise during and after an egg retrieval cycle covers what’s fine and what to hold off on.
After retrieval: fertilization, embryo growth and PGT
Retrieval day feels like the finish line. Biologically, it’s the start of a new race.
If you’re creating embryos, your eggs are fertilized either conventionally, where each egg is surrounded by sperm, or with ICSI, where a single sperm is injected into each mature egg. Fertilization is checked the next day, about 18 hours later.
Then you wait again.
The embryos that keep developing reach the blastocyst stage on day 5, 6 or 7. And this is where the numbers start to drop: not every egg is mature, not every mature egg fertilizes, and not every fertilized egg keeps growing into a blastocyst. Human reproduction is wildly inefficient. It takes a lot to get there, and that attrition is biology, not a reflection of anything you did.
I explain why so many embryos stop growing after day 3 in this video:
For a look at what actually happens in those days, read my behind-the-scenes guide to the IVF lab.
If you’re doing PGT, a few cells are biopsied from the outer layer of each blastocyst (the part that becomes the placenta), and the embryo is frozen while that sample is tested. In my experience, results usually come back in about 1.5 to 2 weeks, though turnaround depends on the lab.
Once you have embryo results, my embryo grading chart and ranking tool and euploid embryo predictor can help you make sense of the terms your clinic uses.
Fresh vs frozen embryo transfer: the biggest fork in the timeline
This is the fork in the road that changes your IVF timeline the most.
With a fresh transfer, an embryo is transferred in the same cycle, usually 3 to 5 days after retrieval, as long as your uterine lining looks good and there’s no reason to hold off, such as a higher risk of ovarian hyperstimulation syndrome (OHSS). You start progesterone right after retrieval to prepare. That’s how you get from first injection to pregnancy test in about four weeks.
With a freeze-all cycle, every embryo is frozen instead. If you’re doing PGT, the testing happens in the background while your body resets: your period usually arrives about two weeks after retrieval, and frozen embryo transfer prep can start from there.
A medicated frozen transfer uses estrogen to build the lining, then carefully timed progesterone. A natural, or “cryonatural,” transfer follows your own ovulation instead. Either way, the prep usually takes about 3 to 4 weeks in my practice.
My frozen embryo transfer timeline breaks down both approaches day by day, and you can map out your own tentative dates with my frozen embryo transfer date calculator.
One question I get constantly: do you need to take a cycle off before the transfer? Not necessarily. In my practice, starting transfer prep with the first period after retrieval is routine, and I don’t make patients wait just for the sake of waiting. If your doctor recommends a break, it should be for a specific medical reason, not the calendar.
The two-week wait: testing after embryo transfer
The dreaded “two-week wait” after IVF is poorly named.
Clinics usually check a beta hCG blood test about 8 to 10 days after embryo transfer. You don’t wait the full 14 days because the embryo was already several days old when it was transferred.
I know the urge to pee on a stick the minute you leave your transfer. (No judgment, I’ve been there.) But a test taken too early can be falsely negative, and if your trigger shot contained hCG, an early home test can pick up leftover medication and give you a false positive. Your clinic’s blood test is the one that counts.
When your beta comes back and you’re trying to understand the number, my guide to beta hCG levels after IVF walks through what it means. And once you get good news, my IVF due date calculator will map out your due date and pregnancy milestones from your transfer date.
When your IVF timeline doesn’t go as planned
This is the part no neat infographic captures.
Sometimes stimulation is stopped because too few follicles respond. Sometimes a retrieval gives fewer mature eggs than expected. Sometimes eggs fertilize and then none make it to the blastocyst stage. Sometimes you need another retrieval before you ever get to a transfer.
I know this one personally.
In 2017, my husband Bobby and I set out to freeze embryos. My ovarian reserve looked okay (not amazing, but okay), and it did not go the way I hoped. On my second attempt, my cycle was cancelled because only one follicle grew. On the third, I got two mature eggs. Both fertilized.
Neither became an embryo.
When that update came in, I closed my office door and cried my eyes out. I felt like my body had failed me. And I felt that way even though I knew exactly what I would have told a patient with my story: low response is a function of ovarian reserve, you did nothing to cause it, and it says nothing about your worth. Despite all my training, I was the patient, with nothing to show for two weeks of injections and a procedure.
That experience changed how I counsel people about IVF. A timeline is useful because it gives you landmarks. It is not useful if it convinces you that your body has failed because your cycle didn’t follow the average.
If a cycle doesn’t go the way you hoped, your doctor may suggest changing the protocol, repeating some testing or moving into another retrieval relatively quickly. What makes sense depends on what happened in your specific cycle. There is no prize for rushing, and no failure in needing to regroup.
IVF is shorter than you think, and it’s okay if yours isn’t
So, back to that first question: how long is this going to take? Less time than most people expect. The injections are measured in days, not months. About 8 to 12 days of stimulation, retrieval roughly two days after your last shot, and then either a fresh transfer within days or a frozen transfer a few weeks later.
But the IVF schedule that matters is yours, not somebody else’s.
Your follicles may grow faster or slower. An embryo may need an extra day in the lab. Your doctor may decide a fresh transfer isn’t the safest choice. You may need another retrieval. None of that means you did IVF wrong.
What helped me, both during IVF and later in pregnancy, was thinking in milestones instead of trying to hold the entire process in my head at once. Get through stimulation. Get to the trigger. Get through retrieval. Wait for fertilization. Wait for embryos. Get to transfer.
One goalpost at a time.
A quick but important note: this post is for educational purposes only, and it isn’t medical advice. Every protocol, every body and every cycle is different, and the person who actually knows yours is your doctor. So please, please talk to them, bring them every question you have, and listen to them over a timeline some stranger on the internet swears by. (Yes, that includes the Reddit thread comparing day-five ultrasounds.)
