So my boyfriend and I had sex on Tuesday and i was on my fourth day of my fertile week and we didn’t use a condom he didn’t cum in me but we freaked out because we weren’t sure about pre-cum and whatever and we ended up going to the store and getting the morning after pill and I’ve been having major cramps since then (and a little bit of spotting) I’m not sure if that’s normal or not since this was my second time having sex with someone and because this is my first time using any type of birth control pill should I be worried ??
