Hi, again!
A few more mamas on Facebook replied to your question.

Mine was removed on a Monday morning, week 37... nothing happened till Saturday morning when my waterbag burst (after a lot of activities!). That evening, I was still 2 cm (I was 2 cm at 23 weeks when the cerclage was placed). I was given induction after induction, lots and lots of contractions (and PAIN!!!), finally dilated till 7cm at 3am Sunday and was told to start pushing. My son was vacuumed and safely delivered at 3.48am. It seems cerclage sometimes causes our cervix to become rigid thus unable to dilate naturally.

Both of mine were right away, but I have found this is very abnormal.
