I just recently had sex we had protected sex. the condom slipped and some of his stuff landed on my inner thigh. i was worried about some getting inside of me should i stop birth control to see if i am pregent or still use birth control?

Sperm are fragile fellows that die quickly outside the favorable environment of the female vagina. I thing the chances of a pregnancy in the cited exposure approach zero. If you want to be pregnant, don't use BC. If you don't, use BC.

Do not stop using birth control unless you want to become pregnant. Chances for pregnancy are negligible in above mentioned circumstances.
