Pinching pain

Kirby • 22. Can't wait for my baby boy to get here! Hurry up August!
All day I've had this pinching pain on my left side kinda feels like it's on my ovary. The pain only happens when I make sudden movements or turn awkwardly and only lasts a couple seconds. Has this happened to anyone else? I have an appointment Thursday, is that too late to see the doctor about this?
