should I go to the hospital

Okay....... So I've been feeling this sharp pain in my vagina and like it hurts to walk I've been feeling it since 3 today I talk to my friend who recently gave birth and she said it could be contractions to go and keep this in mind like I'm 3 1//2 cm dilated 75% efficient and something called -a1 and 2 so any tips I hate driving all over there to be sent home
