this site is flooded with "am i pregnant questions". teens either don't pay attention in sex ED or that class doesn't teach about birth control.
anytime you don't use a "condom" or "the pill" you can get pregnant. use them at the same time. it's total bullcrap if your boyfriend says "i'll take it out on time" and if he says "there was none in the condom... i swear" ect. if you think you aren't ready for sex then trust that feeling and don't do it. yes the best way not to get pregnant is by not doing it.
i'm just tired of the same questions all the time. and they will always get those answers.
