Last month I was tracking ovulation, doctor noticed that my endometrial has upnormal thickness it was 16 mm

Today was my fourth period day the endometrial is 9 mm

Doctor asked for biopsy he have doubts that maybe I have endometriosis.. I have heavy bleeding during period and it's more than 7 days, and I have sometimes spotting
