Sex has been extremely painful for me for years, as a result of my endo. Today, my partner and I attempted penetrative sex. It was painful, but I managed for a bit before we stopped. That was several hours ago, and I've just gone to the loo and found a fair amount of blood in my knickers. I'm not on my period, and I've never had this before.
Does anyone else have experience of this? Should I be worried?
