i usually start my period around the 23rd or most of the time right on the 23rd. my boyfriend and i had unprotected sex and he finished inside me, but i still haven’t hit my period. we had sex the 22nd, so a day before my period was supposed to start. i’m now five days late and freaking out. i’m not on birth control, i haven’t taken any pregnancy tests, or plan b. my boobs are a little bit bigger than normal, but i’ve been super stressed all week so i’m not sure if that’s why i haven’t hit my period yet or if i’m actually pregnant.
