I am very embarressed. I had sex with my friend a day before my cycle started, 26/01/2016. He pulled out just before he came. My cycle was 3 days and very light. On 6/02/2016 I went out with friends, drank a lot and had unprotected sex with another friend. Don't think that he came but are unsure. I had sex again with my friend(first) on 14/02/2016 and 19/02/2016. He pulled out again just before he came. Now it is 01/03/2016 and my cycle did not start yet. If I am pregnant.. who could be the father?

The sex dates are to close together, there is no way to determine who it is, till after the baby is born, and you do a DNA test.

Either could be the father. ANY time there is penile insertion there is the possibility of pregnancy. The only way you will be able to tell who the father is would be with a DNA test after the child is born. You should wait about 1 more week and then you can take a pregnancy test.
