Hurting third trimester 😩😔

I’m currently pregnant with my third baby and I’m in my third trimester but for the past week I’ve been hurting super bad behind where my c section scar is and in my vagina ! I only had a c section with my first child that was in 2016 , my second was a successful vbac , it hurts to walk or even move ! Idk what is wrong I never hurt like this with my others .

Has anyone else ever experienced this before ?
