Is your cerclage your mucus plug?!
Oh wow, I have a cerclage in place as well. I am currently 20 weeks. Did they check you to make sure u hadn't dilated? Did they give u a time frame as to when you may go into active labor? call you Ob as ask is this normal and what med you can take to help with the pain. They may have u come in to check you. How may weeks are u now or have u had your lil one? Congrats!!!
Typically just Tylenol is recommended for the pain- it should go away within a few days. If you are still feeling pain tomorrow- I'd give your doctor a call to see what they say about it and see if they have some recommendations.
