My doctor referred me to have an ultrasound after I complained of ovarian/abdominal pain and bleeding. I had a trans-abdominal ultrasound, which came back negative. I'm very petite and under 25, so was told that they may be able to get a pretty clear image with a trans-abdominal ultrasound. However, I'm still a bit concerned. Is a transvaginal ultrasound the only way to detect early stage cancer, or smaller masses in the ovary? Can I be confident with my results from the trans-abdominal ultrasound?
