Hi. I have had some vaginal bleeding. I am age 58, past menopause. I have seen a doctor and had an ultrasound. There is no thickening of the uterus, and he is following me. The risk is endometrial cancer, and he does not think that this is an issue right now. He thinks there is a risk of the drying and cracking of the uterus, but not cancer. This has been going on for two months, but subsiding. Now, there is a strange discharge, greenish and reddish, but not consistent or every day. Tonight, I passed something hard, rice-like and calcified. What is going on? What was that?
