My friend who is a female senior is bleeding from the vagina again. She saw a gynacologist; but, it started again this morning. She tested negative; but, is waiting for the results of a biopsy. She has a problem with too many red blood cells which is being addressed. They say her uterus is thickened. She is very worried. What could be causing this? She didn t want me to inquire. I thought it was free. So I will wait until she gets a report. I just wanted to alleviate her worrying.
