Pains in the vag?


I had my cervix check yesterday and it hurt so bad! Afterwards I could barely move my legs let along walk. Today is better but still hurts. Is this common? I've have my cervix checked a few times before and didn't have this type of pain? Im 36 weeks could this be labor starting soon? Baby is head down and really low. I have had contractions due to a car accident on the 20th but not within the last few days.
