I had a LEEP conization done about 20 years ago. I had already had my son a few years earlier, and they had been keeping an eye on the cells for a while. We had planned to do a cryo procedure a couple times, but I got pregnant. Then I had a miscarriage, and my insurance changed so I had to find a new Gyn (it was a tough time in my life). It was done under local anesthesia. I honestly don’t remember much pain or discomfort – I had to take some time off of work and take it easy for several days, though. I had semi-annual Pap smears for several years after and they were always clean.
I never got pregnant after that, but I was trying not to; so I can’t speak to the fertility concern from personal experience, but I know they can close the cervix during pregnancy as a preventive measure, called a circlage. When my Gyn and I were discussing my impending partial hysterectomy due to fibroids in 2010, I was amazed when he said they’d leave the cervix in. He felt enough years had gone by with clean results, and there was enough tissue there that I was better off keeping it in place.
My LEEP was done years before they knew what we know now about HPV and its many variants. I always suspected that my husband at the time was a part of the problem, and I now assume that it was a form of HPV. I asked my current Gyn if I should be tested, but he agreed that with my history, we can be fairly certain that I have it; and he says that pretty much any woman over 40 has it if they ever had unprotected sex. Again my generation is different than yours. Did you get the HPV vaccine? Has your Gyn tested you for HPV? If you have a partner, have they been tested?
