I had been with my boyfriend for 3 years... We had unprotected sex, then he told me that he cheated on me... so I rebelled back (which I know wasnt the way I should of handled it), but cheated back on him 3 days after sleeping w/ my boyfriend. I used protection, but now I'm almost 32 weeks pregnant and it never came to my attention that the baby might not be my boyfriends, what are the chances of it not?
