So i started birth control about a month and a half ago, on the second pack. He doesn't use a condom but he does pull out (he pulls out well before he has to cum so i suck his dick/give him a hand job so he cums ON me rather than IN me. Buuut we go for a lot of rounds and he doesnt pee before each round. What are the chances of getting pregnant with pre-cum while on birth control pill?
