I have had irregular bleeding, basically I have had a period for the last 3 weeks with a few days here and there of non bleeding days. I went to the doctor and he performed a vaginal ultrasound. They found something that concerned them in one of my ovaries. They were not sure if it was a possible egg that did not release or something more serious. He put me on birth control pills to regulate my period to see if this would release the egg if that was in fact the problem. If not, he said he will have to do surgery to find out what it is. I have lost 7 lbs unexpected in the last month. I'm very petite and usually have a very steady weight. I am 40 years old with no family history or other problems in the past. Any ideas?
