Girls, pain in the crotch area for two days now, only on one side hurts, thought it was a pinhole but I don't know, can't figure it out. It feels like a needle prick, walking is hard and getting up is difficult. Or is it symphysis pubis? Tomorrow I'll go see a doctor, I don't know if I should see a therapist or a gynecologist or get an ultrasound done. And my due date is just around the corner.
