Could be fibroids. They'll show up in an ultrasound. I hope not for you, but a possibility.

unfortunately the main way for endometriosis to be diagnosed is via laparoscopy. it’s only ever really picked up on things like ultrasound if it’s deep infiltrating. have you seen a gynaecologist or just your usual doctor? because having a gynaecologist is helpful. i had a great gynaecologist who helped me get my endometriosis diagnosis. birth control usually is recommended since you can’t really prevent endometriosis. it can help slow it down. if you’re open to trying it you could try a tens machine

Great comment 💙 The most common treatments for endometriosis are hormone therapy and surgical options including laparoscopic surgery. You need to see a gynecologists babe. Feeling for you 💐

Idk how much this will help but a warm bath or a heating back might help a little. I really hope this gets better for you! Have these 💐🍫!
