Hi ladies, my doctor recently told me he suspects I have endo. I don't know much about it. Yesterday I went to the doctor, he did a quick exam which wasn't too painful, then I had sex. Sex wasn't painful at all, and I definitely wasn't bleeding. But as I was driving home this horrible pain started. It felt like a deep stabbing pain in my uterus area, and through my inner vagina. And I was bleeding horribly, my period ended over a week ago. But this blood didn't look my normal period blood, it was bright bright red, and very thin. I called my dr and he told me to go to the ER and the ER has no idea what it was. Im not pregnant (they tested me) but the ER told me that endo wouldn't be causing the bleeding so he said didn't think it was that. Any idea?
