I think my V is broken 😭

I’m currently 35w 1d and for the past week or so I been hurting like if I did a whole work out on my growing area and my vagina hurts sooo bad... like if I had rough sex none stop for hours... and it’s hard to get up and walk ughhh what’s going on.. my mom said it’s the pressure from the baby but I think it is way too soon!?
