I had my period from 1/2/12 to I think the 5-6/2/12 I had sex with a guy unprotected on the 10/2/12 and again 13/2/12 but both time he pulled out. I started seeing some one else on the 15/2/12 and had sex unprotected and he did not pull out. I found out yesterday which was the 6/3/12 that I am pregnant. Which one could be the father? I usually get my period at the start of every month but this month I have missed it

Either one. The only way to tell for sure is to wait until the child is born and have a paternity test.

The sex was too close together. There is no way to tell at all. You will have to do a DNA test after child is born.

I think it is the first guy bit you will have to see through dna testing.

Like the others have said, there's no way to know. The dates of sex are too close together, and either one could be the father.

You'll have to do a DNA test to be sure.

Like others have said... you have to wait until the child is born, and have both candidates tested to figure out who the lucky individual is.
