User avatar Unfortunately there is not an easy answer here. You could have been fertile during the time frame that covered both the 8th and 14th. The reason it is hard to say is that not everyone ovulates at exactly the 14th day. If you have regular menstrual cycles between 26 and 32 days, your most likely ovulation date would be April 9 making intercourse on the 8th the most likely conception. Sperm can live in the fallopian tubes up to five days. But eggs do not last so long (around 12 to 24 hours). Again, since you don' t know exactly when you ovulated, you can't be sure which it is. Only paternity testing later could most certainly verify who is the father.

I hope this helps, even if it doesn't give you a definite answer. Good luck.
