I had sex with my bf on 3-17-08 and later that nite me and my x had sex.I heard it also depends on whose sperm is also healthier!! My bf just drink beers and go to work that's it...my x(which i just found out) smokes crack and have been for many many years.I then had sex with my bf again on 3-24-08 and then the 31'st.Im now 22wks and some days preggo.Could the sperm from the 17th have gotten me pregnant on the 24th? Since some say sperm can live ffor up to 7 days?I was also on loestrin for 2 mths and about 29 days.I ran out that weekend me and my bf had sex ..we had sex on the 24th and i stopped taking them after march.I went to the doctor for the first time in july and they mesured the baby as 16 wks and 2 days.that lands on the monday me and my bf had sex on the 24th.The doctor said i wood have conceived between the 23rd of march - april 6th!
I was on loestrin24

the chance is 50/50
there is noway to tell what date you conceived on, thats why they tell you you can have the baby 2 weeks befor  or 2 weeks after your due date. sorry but test after baby is born is going to be only way to tell for sure

Get a paternity test when the baby is born. Those dates are too close together to just guess which guy is the father! Sperm can live up to 5-7 days in the vagina. Therefore it's anyone's baby at this point.

I know you are probably not wanting you current boyfriend to know that you had intercourse with your ex but it is in the best intrest of the child to get a perternity test once the baby is born. The chances are 50/50. Good Luck.
