short cervix - 20 weeksì


I went for my 20 week scan a few days ago and asked them to also do an Internal scan to check my cervix. I had letz treatment for precancerous cells a couple of years ago and have been conscious that this could of damaged my cervix. I was told that whilst the baby is healthly..i have a 19mm cervix. it should be 25mm in usual circumstances. I've been given pregesteron pesseries to insert nightly and told I need to be seen by my doctors weekly for cervix measurement as I'm now high risk for pre term labour. I know nothing more at this stage so any comments welcome!x
