Okay so I had unprotected sex with my friend Oct 11 and he came inside of me, i took the first pill 2 hours after, and the second 14 hours after the first, i got the withdrawal bleeding this Tuesday and it's sort of heavy, but I've been experiencing some vomiting, and I feel nauseated by the scent of coffee (And I LOVE coffee :/ ) Is it possible I can be pregnant? Should I take a test in 2 weeks to be sure or am I freaking out for nothing?
