Hi, I am 24 years old since starting my period at 14 I have always had severe cramping which caused diarrhea aswell. I then went on the pill cerazette at 16 years old, I bled on and off for around 3 years trying to settle on the pill, my doctor told me to bare with it. I then stopped having proper periods about 2 years ago, no cramping but just occasional bleeding. Now within the recent two years my periods have returned a normal flow again but they last about 10 days instead of 5, I never have blot clots or severe heaviness. Just a continued flow period. Thing that is concerning me the most is all through my life of having period I have always felt it more on the right side, I used to get a niggling pain in my right ovary before I was due on but a couple of years ago the right pain in the middle of the night was so strong I nearly went to a&e it came in waves and eventually went and I started my period. Now I have a period every 2 months and 2 weeks prior to me starting my period this dull pain ache in my right ovary will return along with diarrhea. On the day of my period and for a couple of days in it's really painful and then disappears as my period disappears. I have had ultrasounds and transvaginal ultrasounds neither showed anything.
