Anatomy scan

Kaitlyn

Had my anatomy scan today at 19.5weeks. Baby was 12oz and 80-95 percentile on every measurement. Dr said measuring 21.5 weeks. I’ve also had lots of Braxton Hicks and lightening crotch. My cervix is still closed but since I had preterm labor with my first we’re starting vaginal suppositories. Has anyone used these to prevent preterm labor?
