Hello, I am 30 years old, 5'0", 120 lbs and have had irregular periods (I would get it about once every 6-8 weeks) since I was 13, and just this year I noticed that I've been spotting between my last two menstrual cycles. I have also noticed that my last two (regular flow) periods were closer together: 28 days and 33 days. My last period was on 5/14 and I am still having brown and bright red tissue discharge. Spotting isn't heavy, but enough to dampen my pantyliner every few hours. I also get very slight cramping in my lower abdominal area during spotting. Is this normal? Should I be concerned?
