| Yes, its 40 weeks from date of last period or 38 weeks from ovulation but this is usually based on regular periods of 28 days and assuming ovulation occurs around 14-16 days.
My period was every 35 days and I would ovulated around 21 days, so my EDD worked out to be 41 weeks from date of last period.
Having said that, anywhere between 38 and 42 weeks is still normal and only baby knows when he/she's popping out, so be prepared! |
