Is there any way that I would get pregnant after protected sexual intercourse, if I accidently touched my vagina unknowingly while my male sig others sperm was still fresh on my finger that made contact with my vagina after we were done with "protected sexual intercourse" and then missed a few days of my mini pill, which I tend to do a lot. Sometimes I get an upset stomach after breakfast and right after taking the pill, and end up spewing my breakfast and the pill, i guess. So that means that the only real protection would be a barriar method, right? Ummmm???
Yes it is possible you could get pregnant that way if it happened at a fertile time. Sperm can enter the vagina manually. The risk is probably low, but it only takes one sperm.
Taking the pill erratically would mean you cannot rely so much on it for contraception, and vomitting the pill is the same as not taking it. So you are right that "the only real protection would be a barriar method".
