Hello, I was wondering if anyone could offer me any advice. For about a year I have been having pains when going to the bathroom (for a poop! Sorry!) but only whilst im on my period, and they are generally worse in the first few days. As the months have continued this pain has also occurred whilst passing wind or even for no reason, but again its only the first few days of my period. The pain is almost like a knife going up inside my bum, and it makes it really hard to go to the toilet because of the pain. Sometimes I'm even crying out it hurts that much. I'm 19 years old, I have been to the doctors, but so far all they've offered me is blood tests which have shown I'm anaemic, and they sent me for an abdominal ultrasound but on the result it said for my uterus "shows no sign of endometrial thickening". The doctors at my GP seem to not want to refer me to a gyno but that's what I feel i really need, but I worry because there's nothing seemingly wrong with me that no one is listening. Makes me feel like I'm going a bit crazy! Obviously I'm not a doctor but I have looked into endometriosis a lot as it's the only answer for my pain I keep coming back to and I worry that the endo is on my bowel. If anyone with similar symptoms who has been diagnosed or is going through similar symptoms has any advise etc I would really appreciate it, many thanks.
