ok so big problemo for me over here, so me and my mans had sex once over his spring break like four weeks ago. And then i got a BAD uti where i was PEEING blood it was awful and i ended up in the hospital. And then, last week i was hitting my sourin a lot and didn’t eat Lol and yaked in the car and it was just bad and i was freaking out cause it was the morning. (and by the way i’m in the pill too and have always been fine). And i was supposed to get my period like that week or somewhere around that and all i had when i was supposed to get my period all there was was brown discharge and sometimes a little blood but not a period period so i got even more nervous. so if u know anything thing could make me feel better cause this anxiety is killing me and am really hoping no one says anything bad i’m just very nervous !
