I've also had CIN3 cells removed from my cervix. At the time, I was told that they were too extensive for laser treatment and so the cells were actually cut away from my cervical wall. That was four years ago, and last year, the ob who does my six-monthly colposcopies told me that if I wanted any more children, I should probably hop to it as women with a history of CIN3 were often prone to recurrences which result in early hysterectomies.
Needless to say, we 'hopped right to it' and here I am 16 weeks pregnant smile. During the first visit to my GP, he mentioned the fact that I'd had the previous surgery on my cervix and noted that I could very possibly have an 'incompetent cervix' as a result. Now, while I don't know exactly what this means, my doc said that the main concern for women with an incompetent cervix was the high possibility of first trimester miscarriage.
Luckily, we've made it past the 'dangerous' first trimester period now ... but the trick for women in this high risk category is apparently to take it VERY easy for those initial 12 weeks. All the best!
