Too close to call as they are only a matter of a few days apart. Unless you knew precisely the day you ovulated, and most women don't, it can be either one's.

Doula, even if she knew when she ovulated remember that sperm can last as long as 5 days in the female reproductive system.

It's possible that either man's sperm could have caused this pregnancy since the window is so close together.

Only a DNA test will tell for sure.

True... I'm just thinking that if she happens to ovulate on the early side, sex with number 2 could be too late.
