Lightning crotch or what?

I’m currently 37+1 and since about the 30 week mark, I have been having such bad pain around my vagina (like the muscles). I have such a hard time describing it but the best I can do is to say it feels like someone with steal toed boots kicked me as hard as they could between the legs and then in the inner upper parts of my thighs. It is at an all time bad right now! It’s really painful to walk and even change positions while sitting or laying down. Also experiencing an increase in contractions but they’re not regular. Is this a sign my body is getting ready for labor soon?
