RanToTheHills - Do take it seriously, but again, no need to worry about it. Even if there is the beginning of anything to be found, they will have caught it very early. The treatment is very much like the removal of a mole. Let us know what your results turn out to be.
Mucky - I am amazed to hear you went from CIN I to CIN III in a couple of months! I was told that each step takes at least a year.
I was positive for HPV, as are practically all women whose smear tests show abnormalities. I worried myself sick about it for a while (am I now 'infected' forever? will it pass to baby when I get pregnant or during birth, etc) but apparently it is very local and you don't have it after loop excision. DH (DP at the time) had to have a little laser procedure so that we would not continue to infect eachother. But that was the end of it.
Apparently HPV infection rate in the overall population in Europe is around 70%. It only turns cells into cancerous ones in a very small number of women apparently.
Conceiving was absolutely no problem (and I was 33 1/2 years old at conception). I had no cervix problem during prenancy or birth of DD. We are not yet trying for another (I'd rather DD starts nursery next year before the next baby comes along) but we are thinking of getting pregnant in early 2008.
I had found it hard to believe that loop procedure would have no bad effects on my fertility or ability to bear children, but apparently it's true.
Good luck on your baby plans.
