Transfer day due date क्यों बदलता है
Transfer day बताता है fertilization के बाद कितने दिन बीते। यह age 266-day fetal development window से subtract होती है।
Day 5 embryo day 3 से दो दिन बड़ा होता है same calendar date पर — day 5 transfer की due date usually ~2 दिन पहले होती है।

Side-by-side comparison
| Factor | Day 3 | Day 5 |
|---|---|---|
| Stage | Cleavage (6–8 cells) | Blastocyst |
| Age on transfer | 3 days | 5 days |
| Days to add (266-day model) | +263 days | +261 days |
Example: Transfer March 10, 2026
- Day 3 → approx. November 28, 2026
- Day 5 → approx. November 26, 2026
Fresh vs frozen: same logic
Fresh या thawed — developmental age on transfer day matter करता है। Storage time extra days नहीं जोड़ती।
Common mistakes
- Wrong transfer type in calculator
- Using medicated-cycle LMP instead of true period
- Confusing retrieval date with transfer date
