Hi Nae,
This may not be the answer you are seeking but I thought I'd share.

I had an infection called chorioamnionitis with Lachie and this is the reason my already weak cervix ( like yourself I had an colposcopy and part of my cervix removed due to abnormal cells) dilated. Chorioamionitis is an infection in the membranes/uterus which inflames and irritates the cervix. Hence dilation and labour occurs. At my checkup I was told that it would be my choice to have the suture with my next pg. My Ob was prepared to do it for me and keep me on and off low dose antibiotics to help prevent infection. He gave me the pro's and con's of the suture but I told him I wanted to do everything I could to save my next baby.

We had no time to prepare ourselves for the next pg. Eight weeks after we lost Lachie I woke one morning with the extreme metal taste in my mouth and knew straight away I was pg. My GP referred me to my Ob- even though I was a public patient he took me on as though I was a private and saw me whenever I needed. At 13 1/2 weeks I had my suture put in and was sent home that day after with no bleeding and antibiotics. I was seen every fortnight by my Ob and inbetween with my GP.

At my 20 week scan my cervix was 2.3cm. My DD was born 9 weeks early due to PE and at my last scan it was 1.2cm. My induction was planned and suture taken out. I dilated 2cm instantly.

I believe that without the suture I wouldn't have gotten as far as I did.

I too think that there has to be some sort of trigger for pre term labour.

My advice to you is to seek multiple opinions. You know your body and what you went through with Nikita. If you feel strongly about it not being a contraction problem then write a letter of request to the hossy you had Nikita at and request a copy of your notes from the time you were in. You will need proof of identity to go with it too. Maybe having a few different opinions will give you a more difinitive answer.
