So I’ve been on birth control pills before and had problems now I’m back on them. Well not even a week after my period I had sex and the next day had some spotting lift pink a little brown was thinking ok just old blood. Well I for got a pill one day andwell not even 24 hrs after forgetting it I start having cramps and more spotting but now itsmostly brown discharge and very little blood. I just had my period only a week ago and here I am with horrible cramps again. Is this normal? What is the brown discharge?
