Can semen bypass the bc pill? Especially if you’re “cummed” in frequently?

Birth control is meant to stop ovulation, it doesn’t matter how much sperm enters since there is no egg to fertilize. As long as you’re taking your pill correctly there’s nothing to worry about :)

If you’re taking it right then no, like Rosie_Rose said it is meant to stop ovulation, but it also does other things like thickens cervical mucus making it harder for sperm to enter the uterus and makes it harder for the sperm to survive if they were to make it there, and if they do there’s no egg to fertilize anyways
