Pains in between thighs/crotch?

Michelle • 22
It started about a week and a half ago. If I spread my legs to get dressed or anything I feel a huge pain in between my thighs/vaginas area. Or if I flip over in bed. I'm 27 weeks exactly, what is it or who else has this? It hurts but it's not unbearable or 24/7 only when opening my legs a bit 🤔😥😥
