Period cramps and watery discharge

Could my fluid be leaking? I've had period cramps since yesterday and I've been getting this water like discharge in my underwear that isn't urine and I felt it come out in a small gush once but the other time it was just a feeling of wetness. I'm 32 weeks. It's not Braxton hicks either. Wondering if it could just be normal cramping and the discharge is just normal discharge?? Idk. I have a dr appt tomorrow morning, so Idk whether or not to call today.
