Cervical Biopsy

Today I got my first cervical biopsy. It hurt like hell :(. The doctor was talking about doing a cryosurgery to get rid of the cells. I read earlier that the cryosurgery could cause scaring and could make the cervix weak. I was wondering how often does the cryo make it harder to conceive? I read that there is a chance of going into premature labor after having the cryo done. I'm planning to start a family one day and I want to get some sort of idea what to kind of expect, I know not every pregnancy is the same.

Also when the Dr. was trying to get one the biopsy spots to stop bleeding but he was having a hard time. Could that cause problems during labor? I mean if he had a hard time getting a little spot to stop bleeding what is going to happen if I go into labor?

I'm probably over thinking everything, I'm really bad about doing that. But I want to learn what ever I can about something.
