HELP!!

HELP!!!

So, for the past 3 weeks I have been bleeding more than normal not sure if sex has anything to do with it. My husband and I had sex on the 8th and I bled from then until the 17. We had sex Friday night and I bled until last night. Then, we just had sex tonight and I started bleeding and looked like if we had sex and I were on my period. I thought it was kidney stones but, it isn't. I was thinking it maybe my PCOS but, would that have anything to do with it? This isn't normal I'm sure. Any suggestions?
