Painful movements

Is is normal to have sharp shocks of pain every time the baby moves? Since last night at about midnight, I've had super bad lightning crotch pain, something that I imagine is cervical pain, but also deep, sharp pains where her head is (she's head down, 33+1). I'll feel a movement, then immediate sharp pain for a few seconds, then it goes away. I figure she's just getting bigger and its causing me to hurt. I have an appointment/ultrasound tomorrow so I'll definitely be bringing it up if its still an issue
