I'm 51, still getting regular periods. My last period was in August. Since the beginning of September, I've been getting clear discharge, similar to ovulation discharge. I also had some bleeding that wasn't due to my period, so my obgyn did an ultrasound, which found a 4.9 cm cyst on my left ovary. He did another ultrasound two weeks later, and it's down to 2 cm now. But my lining is thick. He had done an endometrial biopsy at the end of May for some other symptoms I was having, but that was normal. He cultured the discharge, as there's so much of it, and it was normal. He thinks the discharge is just my hormones out of whack from the cyst. If I don't get my period by mid November however, he wants to do another biopsy of the endometrial lining. Has anyone ever had clear discharge with a cyst? I'm either having bleeding (much less often), or this clear discharge every day.
