IVF Due Date ની ગણતરી કેવી રીતે કરવી

IVF Due Date શું છે?

An IVF due date calculator uses embryo transfer date and embryo stage to calculate estimated delivery date. Day 5 blastocysts add 261 days; Day 3 embryos add 263 days.

RetrievalDate: Egg retrieval date (Date)
DaysToAdd: Days to conception (Integer (266 for fresh, varies for frozen/transfer))
DueDate: Estimated due date (Date)

Frequently Asked Questions

How does IVF dating differ from natural pregnancy?

Natural: LMP used (assumes ovulation day 14). IVF: based on exact egg retrieval/fertilization day (more precise). Due date earlier by ~2 weeks vs LMP-based if using retrieval date.

Does embryo age matter?

Yes. Day 3 embryo transfer = 263 days to due date. Day 5 blastocyst = 261 days. Frozen embryos = date of thaw. Ultrasound dating (week 8–13) confirms, can vary ±3–5 days.

When will I see a heartbeat?

Ultrasound 6–7 weeks from retrieval (5–6 weeks from transfer). Transvaginal ultrasound shows earlier. Early ultrasounds (5–6 weeks) may not show heartbeat yet; recheck at 7 weeks.
