Hi Sparkler, I'm waiting for a scan, mine was booked because of pelvic pains and so checking for ovarian cysts. They also usually measure the thickness of the lining in the uterus and look for any fibroids, polyps etc. and check the bladder. The pelvic exam is to feel for any abnormalities too but not as reliable as the scan. I had a scan 2 years ago and all was clear.
I think we all should have a yearly routine pelvic exam when on HRT but not sure this always happens on NHS.
