Short cervix

MrsSStrip

My cervix have been measuring short for the past 3/4 weeks now. So I’ve been going to the doctors every week now. Last week i went it was a 2.4 today I went it was a 1.2 . I’ve been on progesterone for the last 3/4 weeks inserting it into my vagina every night like instructed but I’m starting to feel this medicine isn’t working any all. Anybody been in this situation before ? What happened ? I’m 25 weeks and 1 day as of today
