I actually had a tear in my cervix that my doctor sewed up during my unplanned c/s. It *can* cause problems in a future labor, but it is extremely rare. My dr said about 1 in 200. It's called a stenotic cervix. At a point in your labor when your cervix stops dilating bc of scar tissue, your mw or dr goes in and massages cervix w/ a little epo or something like that. Both a midwife (online) and a dr said it would hurt, but it's a lot better than a c/s!!! I wouldn't worry about it, but if it reassures you, do some research on stenotic cervix. I found some more info on birthlove (I think).
