Hi, I have had irregular heavy periods since they started when I was 14, I am now 30, I had been on the pill for 12 years and they became regular, very light and lasted 5 days, I stopped the pill in an attempt to get pregnant in 2008, they returned irregular and heavy after nothing at all for 9 months, I then finally became pregnant and had my son in dec 2011 via c section, pretty straightforward other than my pelvis was too small for him to be delivered naturally so he needed a little help :) since his birth my periods were regular but extremely heavy for 5 months and then became irregular once again but my question is this ... I have a lot of pain in my right side around that time of the month before and after my periods which resembles a stabbing pain , it is so painful I have ended up in a and e and had my appendix removed 6 wks ago as they thought this was the cause but I came on a week before the pain and I have just finished a period and now the pain has returned again :( they did query fluid on the ovary before removing my appendix which was apparently inflammed, I m confused and fed up , please can you help?

Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You had irregular periods since monarchy, at 14 to 30 now. Used pills and you are alright. When you stopped pills again they are irregular and heavy, recently had a child. Now as the pain returned the doctors thought it may be appendix and operated for it. Again there is pain after period. Operated doctors said that there is fluid over the ovary, and it is inflamed.  In the Beginning irregular periods may be due to anemia, latter after delivery it may be due to infection, so accompanied by pain. anyhow you got operated for appendicitis, the doctors would have removed the ovary of right side when they have a doubt.  As the pains have returned you can try medical treatment in guidance of a gynecologist for ovarian problem, and anemia.  Wishing for a quick and complete recovery.  Best regards.
