Cervix making a disappearing act!

Addiana • Found out we are expecting on my husband's 31st Birthday! August 26, 2016... 👼🏾👼🏾👼🏾🌈👶🏽 Due date May 7, 2017
Has anyone had a shorten cervix and it's almost gone but go to full term? I'm at a 1.1-1.2cm and 20 weeks along. But my cervix had depleted from 3.5cm to 1.1-1.2 in a month. I do have a cerclage so my doc said it will do its job and has done so far and I have to bee seen once a week now. Just looking for some happystories  if any. Thanks in advance
