Well, when was the last time you saw your gynecologist?
The thing is, it CAN be a signal of an infection, that kind of soreness. have you had any other symptoms? Any itching, any unusual discharge, any burning or trouble urinating, etc?
If so, then get in to see your GYN. if not, it's fine to wait a few days, though if you find you're still sore next week, or have any new symptms, march yourself in.
