Severe pain lower left abdomen

Not sure what’s going on. I’m having a lot of pain the last hour right by my pelvic bone on the lower right side of my abdomen. I’m also feeling jolts from the baby right on my cervix and I’ve had an increase in discharge. Is this normal at 35 weeks or do I need to go in? I don’t have a regular ob, I go to the hospital for my appointments and they never gave me a number to call for questions.
