I am 50 and still having regular periods. Recently I had an episode of heavy bleeding so bad the gyno sent me for d and c that day. All went well, bleeding stopped and pathology came back negative. One week after d and c had another transvaginal ultrasound and it showed "up to 16mm thickening". Is this normal one week after d and c? Also showed various ovarian cysts including complex cyst thought to be hemorrhagic.
