35 weeks & my vagina aches??

I’m 35 weeks with baby #2 & I noticed today that my whole vagina aches. It’s not that feeling of “oh we were a bit too rough during sex” (which wouldn’t be the cause anyway - it’s been quite a while since we last did the deed) but more like the entire thing feels like it’s having a muscle cramp. It’s so hard to explain...

I don’t remember this feeling with my first. Although I did get very swollen & had to sleep with an ice pack in my panties but that was more of a throbbing sensation.

This is definitely achey & not throbby.
