Polyps and subseptate

Su

Hi anyone on here have polyps and a subseptate uterus? For years I was told I had a bicornuate uterus and cysts but today I find out different and about endometrial I'm so mad because they could have dealt with this sooner and me having miscarriages and bleeding inbetween every month and constant pain.in total I've been trying to conceive #2 for almost 8 years, I have abnormal cells which I go every year to be checked and last time had a biopsy.
