I have a short cervix & already a cm dilated so I'm taking progesterone vaginal to prevent my cervix from opening even walking for so long my cervix can open I stop taking them at 34 weeks & whatever happens happens at least I'll have my baby 10 mins away from me then 1 hour & 15 mins away even tho I really would like him to make it at least to the 37 weeks..
