I am 46 and have been having pain in my right ovary for at least 5 months. It's started as an occasional pain and I chalked it up to a cyst that would go away. My periods have always been very normal and routine. But this month I skipped my period and the two previous ones were much lighter than usual. The pain in my ovary has gotten much worse so I went to my doctor two weeks ago about a week after the missed period. She sent me for a vaginal ultrasound and they couldn't see either of my ovaries but said my endometrial lining was thick .. 16mm. So my doctor sent me for a CT scan and the scan came back unremarkable with no problems detected other than the thickened lining. There was documentation about other specific organs being clear but no mention of my ovaries. I have had extreme stomach bloating for the past month as well. My Dr prescribed Prometrium for 10 days to make me have a period then wants to do a follow up US. My mother had uterine cancer at age 28 and a complete hysterectomy. I am concerned about Uterine and Ovarian Cancer. If my ovaries weren't seen on the US or CT is it possible I could have Ovarian cancer? Would it be reasonable for me to request a CA125?
