One of the hardest parts of starting IVF isn’t the medication or the appointments — it’s not knowing what any given week will actually involve. A full cycle typically runs 4 to 6 weeks from the first injection to the pregnancy test, and while every protocol is personalised, the broad sequence of stages is the same for almost everyone. Here’s what that timeline actually looks like, stage by stage.
Stage 1: Baseline Testing and Stimulation Start (Cycle Day 1–3)
Baseline ultrasound and bloodwork —
A few days after your period starts, a vaginal ultrasound and blood test confirm your ovaries are resting (no cysts) and your uterine lining is thin — the green light to begin stimulation.
First stimulation injection —
Once baseline is normal, you begin daily subcutaneous injections of FSH/LH (gonadotropins) that encourage multiple follicles to grow at once, alongside a second injection that prevents premature ovulation.
The Core Fact
The active injection phase generally runs 8 to 12 days — but the exact number of days depends entirely on how your individual follicles respond, not on a fixed calendar date.
Stage 2: Monitoring and Follicle Growth (Day 4–12)
Over the next week to ten days, you’ll return to the clinic for 4 to 6 short monitoring visits (15–20 minutes each). Each visit checks your follicle sizes, uterine lining thickness, and hormone levels by ultrasound and blood test. Your medication dose may be adjusted after any visit based on how your follicles are responding. Monitoring continues until your leading follicles reach an average size of 18–22 mm — the signal that they’re mature enough to trigger.
Myth: More monitoring visits mean something is going wrong.
Fact: Frequent visits are the normal, expected part of the protocol — they let your team fine-tune your dose in real time so as many follicles as possible reach the right size together.
Stage 3: Trigger Shot and Egg Retrieval (Day 12–14)
1. The Trigger Shot
Once follicles are ready, a precisely timed trigger injection matures the eggs and starts ovulation. Most women ovulate 37–38 hours later — so the exact clock time of this injection matters and is set by your clinical team.
2. Egg Retrieval (~36 Hours After Trigger)
A short procedure under sedation, usually under 20 minutes, in which a needle guided by ultrasound collects fluid — and the eggs inside it — from each follicle. You go home the same day, typically within 60–90 minutes of waking up.
3. Recovery
Mild cramping and bloating are common for about a week. Rest is advised for 24 hours; most normal activity, apart from vigorous exercise, can resume the next day.

Every protocol is personalised — the clearest way to know your own day-by-day plan is a consultation built around your specific hormone profile.
Stage 4: Fertilization and Embryo Development (Day 0–5 After Retrieval)
Day 0 — Fertilization —
Eggs are combined with sperm within hours of retrieval, either by conventional insemination or ICSI. Fertilization is confirmed the following morning — on average, 70–90% of mature eggs fertilize.
Day 2–3 — Cleavage stage —
The embryo divides into 2–4 cells by day 2, and ideally 6–8 cells by day 3. Some transfers happen at this stage, depending on the clinical picture.
Day 5 — Blastocyst stage —
The embryo has grown to hundreds of cells and reaches the most advanced pre-transfer stage. Most fresh transfers, and PGT testing when used, happen at this point.
Stage 5: Embryo Transfer
Whether your transfer happens on day 2, 3, or 5 — or is a frozen transfer at a later date — the procedure itself is brief and needs no sedation. A thin catheter guided by ultrasound places the embryo into the uterine lining; most patients compare the discomfort to a routine Pap smear. You’ll rest for about 10 minutes afterward and can typically go home or back to work the same day.
Worth holding onto: A fresh transfer isn’t always the plan — freezing embryos for a later transfer, or testing them first, is a normal and often deliberate part of many protocols, not a sign of a problem.
Stage 6: The Two-Week Wait and Pregnancy Test
Hormonal Support
Progesterone and, sometimes, estrogen support the uterine lining after transfer — usually as tablets, vaginal suppositories, or injections, continuing into early pregnancy if the test is positive.
The Blood Test
A blood hCG test, drawn 9–14 days after transfer, confirms whether implantation has occurred. A positive result is confirmed with a second hCG level 48 hours later to check it’s rising as expected.
First Ultrasound
Once hCG levels are confirmed rising, a first pregnancy ultrasound follows within 1–2 weeks to check the pregnancy’s location and progress before you transition to obstetric care.
Every stage has a purpose — knowing what's coming makes the waiting easier to carry.
Frequently Asked Questions
1. How long does a full IVF cycle actually take?
Most cycles run 4 to 6 weeks from the first stimulation injection to the pregnancy test, though this varies depending on your specific protocol and how your body responds to stimulation.
2. How many monitoring visits will I need during stimulation?
Typically 4 to 6 short visits over 8 to 12 days, each involving an ultrasound and blood test to track follicle growth and adjust medication doses as needed.
3. Is egg retrieval painful?
The procedure itself is done under sedation and takes under 20 minutes. Afterward, mild cramping and bloating for about a week are common, but the sedation used is light enough that most side effects resolve by the next day.
4. Why would an embryo be transferred on day 5 instead of day 3?
A day 5 (blastocyst-stage) transfer allows embryologists to watch embryos develop longer, which can help identify the strongest ones, and is required if genetic testing (PGT) is being done.
5. How soon after transfer can I take a pregnancy test?
A blood hCG test is typically done 9 to 14 days after transfer. Testing earlier with a home urine test can give an inaccurate result, so it’s best to wait for your clinic’s scheduled blood draw.
