Endometriosis???!

recently i’ve been telling my doctor i had severe cramps and heavy bleeding. she did the ultrasound and nothing was abnormal so i thought maybe i was overreacting. well this tissue like thing passed through me. i’ve never felt birth but i am pretty sure this was damn close. i sat on the toilet and my back was on fire and my cramps were so bad i couldn’t sit up straight until i felt this slide out and IMMEDIATELY my pressure and cramps went away it was very weird. i have an appointment on friday with my OBGYN

i’ve had plenty of clots before and they do not cause me much discomfort but this wasn’t a clot it almost felt like a liver (or what i think a liver feels like) or a piece of my uterus (idk i’m not a medical professional)

wondering if anyone else had something like this, i am so scared the longer this goes untreated i will not be able to have kids.
