Has anyone had cryotherapy done on their cervix before they got pregnant?

I had my cervix froze (cryotherapy) 6 months before I got pregnant. For the recovery, they told me I would have watery discharge for 2-3 weeks. But about a week or so after the procedure, the part of my cervix that they froze fell out! And I mean the whole part that they froze! Tmi but it was about the size of around a soda can and about 1 inch thick. I keep forgetting to bring it up to my doctor but I for sure am in a couple days at my appointment. I just wanna know if this happened to anyone else. I tried to Google it and nothing shows up. It only shows about the watery dishcharge.
