So much pain at 36 weeks

Melandri

Hi everyone. I'm having the worst back, upper thigh and stomach cramps but it's only on the right side.. It hurts so bad but whenever I google my symptoms it just says it's braxton hicks. I've had no other symptoms of early labour. Any idea what this could be? I have an OB appointment on Wednesday so I just decided to wait it out instead of going to the hospital now.
