Hello! If you are having internal bleeding does your doctor know the source of the blood? Are you passing blood in your stool? Also could you be more specific about the lump in your stomach. Is it in your abdomen or pelvis? If you are being referred for a pelvic ultrasound it would seem to be they are looking for the source of pelvic pain and vaginal bleeding? Given a history of fibroids, it could be that. If you could be a little more specific, I would be happy to respond. Be well.
