I went to the doctor about my ovulation pain and she is sending me for the CA125 blood test. She said my symptoms don't sound like OC. She is also sending me for an ultrasound. Now I have read up about the blood test and there are other reasons for elevated results apart from OC, including endometriosis, which also could account for my symptoms. I am really scared of getting this test in case it comes back positive and then o have a long wait to find out whether I have cancer or not! I'm wondering whether it would be better to wait for the ultrasound? Would that show if I had a tumour?
