A little bit about myself, I am 22 years old and have had my period since I was 14 years old. Almost immediately was put on birth control due to have an ovarian cyst and heavy painful periods. I did not have much problems with this until about 7 months ago. I started getting pain in my left ovary like clock work 1 week after my last week of birth control pills (1 week after my period). It is an aching pain that last usually a week or so, sometimes longer. I went to my doctor and had an ultra sound done which came back normal. My doctor told me just to come back if I had pain that worsened. The pain is not horrible but it is frustrating that it continues to return every month. Taking Ibuprofen doesn't seem to help. Using a heat pad helps temporarily. My doctor previously had suspicions of endometriosis but said that testing for this is expensive and wouldn't be necessary unless I had problems conceiving. I was taking Ortho tricycline (sp?) but switched to Yasmin at the start of this cycle in hopes that within a couple of months it will take away the reoccurring pain. Has anyone experienced something like this? I do have cramping during my periods but not nearly as bad as it used to be pre-birthcontrol. Does this sound like endometriosis? Is there anything I could possibly be doing to try and stop this pain from coming every month? Please help as I have grown completely frustrated and I don't think my doctor is really caring to help.
