HELLPPPP ! ( sorry if its tmi )

Okay ladies I need help, I’m really worried about myself. So about 3 days ago I had a little bleeding and I thought my period was about to start , although it would’ve been 2 weeks and a half early .. the bleeding has stopped and I just get little stains now and then but I get a brownish discharge that smells so bad. Does anyone have a clue on what it could be causing this? What should I do?
