What's happening to me ?

Amy

My periods were very irregular when I was younger. I got put on birth control when I was 16 and been on it since. (22) I stopped birth control in may so we can start trying to conceive. We started ttc right away. I had a period may and June. July I spotted in place of my period. August I had nothing. I am on cycle day 80 and for the past 4 days I have had this discharge with little bit of blood in it. Not every time I pee but a couple times threw the day. Anybody know what this could be ?
