My boyfriend and I were having sex in my car and I just started taking pill like 4 days ago. But he pulled out and came on me but it dripped all the way down from the top of my vagina to my butt crack and onto my seat. How likely would it be for me to get pregnant?? If I keep taking the pill and I end up not getting my period when I'm supposed to should I be real worried or just figure it's the BC pill
