Re: bleeding after endometrial biopsy normal?
I've had two of these done for the same reason - heavy long periods. You are going to have some bleeding from the biopsy. My first one - it was a little bleeding and spotting for a few days. The second one, I was on one continual heavy period for a month straight. My GYN had to give me Provera to stop the bleeding so she could do the biopsy - then I bled again from the biopsy. It finally did stop in a week or so.
I think since your period was due, then that's probably what's happening, but if your concerned, give your Dr a call.
My results were all normal, and now it's been a year since I've had it done, and my bleeding is more regular - and I'm starting to miss my periods (finally).
