My last lmp was on May 4th, 2016 and my period was only 4 days. I had sex on May 11th, May 25th and May 27th. My due date February 8th, 2017. So I'm currently 16 weeks. When did I conceive?
Hi Guest,
You had sex on days 7, 21, and 23 of your cycle. You will normally ovulate between about days 11-16. Sperm can survive up to about 5 days - MAX. The egg is only viable for up to about 48 hours.
But, conception is not immediate. You likely got pregnant from having sex on the 11th but you didn't actually become pregnant until several days later at least. It depends upon a great number of factors including when exactly you ovulate which can't be known after the fact.
The 21st and 23rd, are well past when you'd be expected to ovulate and the egg was very likely NOT viable.
Your due date is 40 weeks from May 4th. That is exactly how most doctors calculate it. It does not indicate when you conceived.
Hope it helps.
