Endometrial thickening on ultrasound

Eboni • Happy 😍, TTC with endometriosis😣 Mommy of 1 👦🏽 (10/07/2011) 1 👼🏾😓 (06/03/2006 - 06/10/2006)

I went to the doctor and got a ultrasound. They told me my Endometrial thickening suppose to be 3 normal mines is at a 13..... does anyone knows what causes the uterus to become thicken like that? She told me not to worry because I will be having surgery for it to see the cause. But it also causing me to not conceive.
