Well, first of all it would have been a little easier to understand what you were asking, if your whole paragraph had punctuation. Second, if you had sex on the 23rd, and 24th, then with a different guy on the 25th, and you are indeed pregnant, chances are it could be either guy.

My suggestion to you, is to decide which guy you want to be with. Then when the child is born, have a paternity test to find out which is the father. After that, if you're not with the father of the child, make sure that the child still develops a strong relationship with his/her biological father.
