Has anyone had experience of extended bleeding (more than 6 months) on the patches? I started HRT last April aged 55 after about 3 years with no period. At first things were ok ( apart from shortage of patches), but from September onwards I've been having regular bleeds each month which seem to be increasing. Saw a gynacolagist in Jan who did a full examination and ultra sound and thought everything was ok but though my problem might be not changing patches on the correct day, so we agreed I'd monitor for a couple of months. Literally a week later I started bleeding again and had bad period pain and night flushes again! I've seen the gynacologist again and he has now booked me in for a hiscoscopy and biopsy as he feels the bleeding has been going on for too long now, and told me to stop using the patches. He's suggesting if the microscopy is ok that I have a mirena coil instead. I'm now worried sick it's something serious. Anyone else had a similar experience?
