i'm not sure if i got my period or it's implantation bleeding. i'm on birth control but i had a mess up and that day my boyfriend came in me. it was about 2-3 weeks before i should've gotten my period. before my period and even now ive been feeling really weird, having too pee a lot, super nauseous, heightened sense of smell, super tired, mood swings. i usually get my period on tuesday's with my birth control, on tuesday when i should've gotten it there was only a bit like a spot during mid day and then today i only had a small amount on the pad too but every other time i've checked and changed there was nothing. when there is that small amount of blood it's red but the first small spot was like pink ish. any help/ advice is appreciated, thanks!
