I have just recently found out that I have stage 4 endometriosis. All I know is my bowel is completely connected to my womb. Last week my gynecologist put me on prostrap injection, But today I started bleeding is this normal. I rung my gynecologist and they said it was normal, they said I was just starting to go through menopause. I'm hating it already, I thought we wasn't supposed to bleed whilst on this injection.
