So I'm abit confused whether I'm having implantation bleeding or my period . I've never had penetrative sex but me and my boyfriend do fool around but stay safe . My 'period' came 5 days early and I had my usual period symptoms (sore boobs ,mood change ) at first my period was light pink then gradually it got darker . The next day I started birth control pills for the first time and I was wearing a tampon . My period leaked through my tampon but after that it didn't really fill as much . My period has been varying from red to pink to brown and sometimes it's heavy and sometimes it's not and I'm still having cramps. This isn't my usual flow but could it be because I'm taking birth control for the first time ? Pls help x
