Hysterescopy and endometritis

Patient: I had a hysterscopy done last week on day 6 of periods. The doctor said there was lot of blood and clots that had to be removed through suction before she could get a view of the uterus, which was unusual according to her. She removed some white tissue and small polyps during the procedure. The histopathology report suggests endometritis and some benign polyps. What could be the reason of the blood that had to be removed before accessing the uterus? do i need further medicines for curing endometritis and also would it be a problem in case i get pregnant?

Doctor:
