Hysterectomy opinions/experiences

Hey all! I had a CKC 2 weeks ago and had my post op today. Dr. recommends a hysterectomy. My biopsy was 3.5cmX3.5cmX1.0cm and the margins were clear but within millimeters. Diagnosed with HSIL (CIN3) and AIS with extensive endocervical gland involvement. I just want to know if you guys had your hysterectomy through the belly button (LAVH) or the other way? What do you recommend? Does LAVH cause any risk of any abnormal cells spreading? (I was told it can.) He didn't say whether he wanted to take the ovaries or not. Do they usually take them too? I have an appointment for ultrasound on February 5th to measure my uterus as it was (probably is) enlarged and if it is too enlarged, LAVH isn't possible. GIVE ME ANY ADVICE YOU CAN THINK OF AND PLEASE TELL ME YOUR EXPERIENCES! I have never considered a hysterectomy and don't know what to expect.
