Twitching around cervix?

T. • High risk pregnancy with baby #1, trying to keep my angel baby!
Hi, has anyone felt what feels like twitching around your cervix or vagina when pregnant? Im almost 23 weeks and I have felt this off and on for a couple weeks. Most days not at all and some days kind of alot. I asked my Dr about is and she gave a vague answer just saying she wasn't sure but if it happens alot in an hour to call.
