Im 18 years old and normally have a very regular period but the most recent had i one was different, i didnt get any cramps like i normally do, no back pain, i didnt break out and my boobs didnt hurt at all. A couple days before it started I had a lot of brown discharge and then it slowly developed into a lot of blood & my flow was a lot heavier than usual. When my period finally stopped the brown discharge didnt. It been a week since the blood stopped and the brown discharge is still there. I had sex 2 weeks before this all this happened. Should i be worried?
