Popping sensation from cervix but no fluid

Judy

I’m 32wk1day, I’m high risk for preterm birth, I’m already 2cm & 50% effaced and this afternoon I felt a pop come from my cervix (wasn’t baby hiccups or anything like that) but no fluid came out, this is baby 6 and I can’t recall this ever happening before!

Has anyone else experience a popping sensation coming from your cervix at all?
