Hey all: I realize this is quite an old thread, but I figured it was worth a try. I'm 13 weeks and 2 days pregnant with mono-di twins (from IVF - a single embryo transfer that split) and was just found to have a short cervix at a scan today. 2.3cm. My OB did a great job running down the risks. For now she is advising the wait and see approach with advice to take it easy and avoid heavy-lifting, etc. I'll have another scan in 10 days.
I had an easy and successful singleton pregnancy with no cervical complications so this is coming as a bit of a shock . . .
Any advice would be exceedingly appreciated. We are, of course, quite worried.
