Short cervix below 15mm, happy ending?

Hi everyone, I tend to be a reader and not usually one to post but in one week my cervix has gone from 20mm to 11mm and would love your support. I’m taking progesterone suppositories vaginally (for almost 3 weeks now since diagnosed with a short cervix) and was told today that it’s not advisable to do a cerclage which I actually was hoping to avoid so I’m okay with that. I’m pretty researched on the topic, but would really benefit right now on some happy endings of women on here who have had low measurements and still got pretty far in their pregnancies and had healthy babies. Doctor said no bed rest because that does more harm than good. Everyone is different though so not trying to get second opinions, just some positive stories :) Thanks! -K
