With DS1 I had a cervical check at 30 weeks due to contractions. I wasn't dilated at the first check but I was at the second check so I got the preterm labor work up (and bed rest!)

I always thought that the manual exam with DS1 at 30 weeks led to my dilation so I declined any checks until 36 weeks with DS2. I had the cervical lengths taken by ultrasound at 20, 24, and 28 weeks though (all fine). I ended up 2cm at 36 weeks despite tons of rest!

This time I had cervical lengths taken by ultrasound at 16, 20, and 24 weeks (all fine). I have contractions but don't want any digital exam until 36 weeks again. Hoping to avoid one!

Did you have cervical checks before 36w? Why or why not?
