When I found out I was pregnant I was about 5wks this was on the 15th of June.My cycle went off around the 2nd or 3rd of May.I had sex wit my ex on the 6th and 13th of May and on the 21st wit my boyfriend.My due date is Feb. 3rd.is there anyway I could find out when I got pregnant

No, due dates are merely educated guesses. You will have to wait till the baby is born and do a DNA test to find who is the father.

I had sex with my ex on the 6th of may(didn't pull out) and on the 13th(he pulled out).My cycle came on around April 29th and went off around the 3rd May.When I found out I was pregnant I was about 5wks this was on June 15th. I had sex with my boyfriend on the 15th 21st & 28th of May. Is there anyway of figuring out when I got pregnant. My due date is Feb. 3.can someone please help me

It's all about guessing and estimates. " woman gets her period usually once every 21-40 days. In between her periods, the woman ovulates (she releases an egg). If the egg makes a love-connection with any sperm, it gets fertilized and she might be pregnant. However, if the egg doesn't hook up with any sperm, the egg leaves the woman's body and she gets her period like usual--no pregnancy. Sperm leave a guy's body in his and pre-. In order to fertilize an egg, the guy must ejaculate the sperm inside the woman's vagina.

So, women are most likely to get pregnant around the time they release an egg. Ovulation happens around a week after your period until a week before your next period. But don't count on it! Your period might not be that regular, and ovulation can happen at any time, even during your period. Plus, sperm can live in a woman's body for days waiting for the egg!"

If this is about paternity - and I assume it is - you have to wait until the baby is born and DNA can be conducted.

"Pull out," of course, is not effective.
