Hi, I am not sure who fathered my baby. I slept with a friend 11th, Feb, 2013. Then got with my current partner the 18th. My first day of last period was 10th Feb 2013. My baby was due 17th Nov. My cycle is normal each month. I think its 28 days. I slept with my friend on the 2nd day of my period. Who could the father be?
