Weird period cramps/vibrating vagina

[carsty]

Hi there, I have only fell pregnant once after 3 years and fertility checks (ongoing) but this sadly ended in a miscarriage. Fast forward 7 months now im currently cramping so definately expecting AF. However, 2 nights ago I experienced atrange sensations along with normal cramps. It was like down there was vibrating but it was more inside or possibly referred from else where but its been happening on and off. Has anyone had this before and is it normal AF cramps. Today im actually due AF but i think i may have ovulated late so expect it either tonight or over the weekend.
Also i recalled when i was pregnant i honestly thought my period was coming due to cramps so thought nothing of it but I wont get my hopes up yet and this new sensation is odd to me. If af do not show by mon ill consider a test.
Sorry for the long post.

I get the vibration feeling too. Sometimes it's just in the "lips" sometimes it's my entire pelvis. It usually happens around my period. Not every single month but 3-4 times a year. I've never been pregnant so I wouldn't assume it's a pregnancy thing. I think it's just a random nerve being stimulated somehow during your period and your brain interprets the signals as vibration.

@DoAWheelie Thanks for your response and sharing your experience. I also considered it cud be as you said or thought I pulled something, which might be causing these weird spasms/sensations.
