  1. Looking for a little assistance here. I just had my first post-myomectomy ultrasound and here are my uterus measurements: 9.25 x 3.6 x 4.02 cm. This is smaller sized than pre-surgery, however I’m not exactly sure if it’s back to normal yet. I will get my official outcomes next week, but I was simply questioning in the meantime. Anybody know what a normal size is expected to be?
