My last period was Oct 10-17th, I used to have sex all the time with my ex, my ovualtion days were 20-24th. I then had unprotected sex with another guy on the 29th. I googled & googled, it said I was most likey to have gotten pregnant around the 24th. My due date was July 16 2012, She was born May 22, 2012. At 31 weeks. If you can help me figure this out it would help soooooooooo much (:
