@Twittlebee I am so so sorry to hear about your losses, your strength really is an inspiration!!
I had the scan of my cervix yesterday and they said they look for anything over 20mm and mine was 45mm
so they said very thick. They still want to scan me in 2-3 weeks as they said that could change so just to keep an eye.
I had a meeting with a consultant and they said that my original cesarean scar has bad scar tissue also with a sack of fluid behind my scar. They said it looks like a much newer scar than a 5 year old one.
I wanted to go VBAC as I am petrified to have a section due to a bad experience, but they said that due to my scar I have a very high chance of having to have an emergency section or a uterine rupture so she strongly advised me to have an elected section, so I have taken her advice and decided that is what I am going to do. 
My due date is 14th June, so the section will be booked between 7-12th.
20 week Scan is next Tuesday 28th Jan, oh my time is dragging!!! I cant wait until that is over. My friend said "thats only a week away it will fly" they just don't understand how stressful this scan is and how time drags leading upto it.
Anyone else have a scan that day or close?
