Hi! I'm A 22 Year Old Female And Haven't Had

Hi! I'm a 22 year old female and haven't had a period since November (always had irregular periods, plus it was a stressful time so I didn't think much of it). I recently had a period exactly two weeks ago but I haven't stopped bleeding. It's very light flow but hasn't really let up. I am overweight but exercise regularly. There's no way I could be pregnant either. Is there something I can do at home to remedy this?
