For the past few months I have been having very heavy bleeding. Not only that I have had 3 periods in the past month lasting from 7-11 days. I had a vaginal ultrasound done and it came back negative but I had a CT scan that showed an midly enlarged fibroid uterus. I don't know which one is correct. As invasive as the vaginal ultrasound was I would think if I had fibroids it would have showed. PLease advise.
