When I first got my periods at age 13 I would have really heavy bleeding and would bleed again a week after my period finished. This was as heavy as the last. I was put on the pill at 15 and my periods became light and relatively regular. I would have heavy brown discharge between periods. At age 20 I had Implanon put in and my periods became heavier, painful and I would get really bad PMS. My cycles were quite long 35-40 days but I would bleed between periods and get brown discharge a lot. I can not do sit-ups or bend over too much otherwise the brown discharge comes and I get cramps. I am now 26 and in January I had my 2nd implanon taken out as my husband and I wish to have a baby. My last 3 periods have come around the 35 day mark, and are really painful yet I barely bleed. I have been getting brown discharge and blood stained mucus in between and if I do any ab work at the gym it starts. I do 2 weight sessions and 1 cardio session at the gym per week. I am on my feet all day at work. I never get sick,but I do feel tired a lot of the time and get headaches. (I think this is from glangular fever when I was 19 though) Am I likely to be still ovulating? What is most likely causing my bleeding/discharge?
