I want to know who could have fatherd my son. I think thats its my bf baby. Please help! oh i usually have a 26 day cycle if that helps any.

Answer
Hi Neenee,

Going by the information you gave me, the likely date of conception is anywhere between July 7-11.  Unfortunately, because you slept with two different men during that time, it is impossible to tell for sure who the father is.

The fact that your cycle is usually short does make it more likely that you conceived in the July 7-9 range - which is in favor of your boyfriend being the father. If the 2nd guy didn't ejaculate, it does make it less likely for him to be the father but it doesn't rule it out, especially if you think that he might not be telling the truth about whether or not he ejaculated.

I think it's more likely that your boyfriend is the father, but unfortunately I can't tell you for sure who the father is. I would suggest a paternity test after the baby is born to confirm for sure.

Sincerely,
