🇮🇳 For Indian parents: Under the PC-PNDT Act 1994, it is illegal for doctors or sonographers to reveal a baby's sex in India — with penalties up to 3 years imprisonment. That's why Indian parents use fun prediction methods more than anywhere else in the world. This tool is provided purely for entertainment — the same way people worldwide use it before their 20-week scan.
Understanding Your Pregnancy Weeks
Pregnancy is measured in weeks from the first day of your last menstrual period (LMP) — even though fertilisation actually occurs about two weeks later. This means that when your period is "late" by one week, you are technically already 5 weeks pregnant.
A full-term pregnancy lasts between 37 and 42 weeks. Your estimated due date (EDD) is calculated as 280 days (40 weeks) from your LMP. The due date is based on Naegele's rule, which adds 9 months and 7 days to your LMP.
