I’m 17 about to be 18 on October 30th my boyfriend and me had sex yesterday but he didn’t pull out and my ovulation start today I ask him if he would be ok with him if I take a pill like a plan b or something just as a precaution that I don’t get pregnant but he says he doesn’t want me to but I just need an opinion cause I don’t know what to do exactly.
