When I had my last ultrasound done my uterus was a funny shape. It bulged out at the top. My gyn thought it was the base of my uterus but he wasn't sure exactly what it was. I know I have endometriosis for sure but I think I may have uterine fibroids too. Not sure. Can fibroids change the shape of your uterus on an ultrasound? Can anyone help me with this please?
