Help advice needed asap

I’m 35+2 today. I went to my doctors office because I’m having regular pains and pressure lasting about 1-1.5 minutes and occurring every 5ish minutes. It feels like a tightening at the top of my stomach and an intense pressure in my pelvis. I didn’t see my regular doctor, as he was gone for the day. The doctor I did see used a speculum and looked at my cervix. He said it wasn’t dilated, but he never once physically examined me. I’m still in pain, it’s gone from being about every 10-15 minutes to every 5ish in the last two and a half hours. The pain is getting more intense and I can’t breathe when it’s happening. I feel like I’m overreacting. I’m not leaking fluid but I am in pain. Should I take what the doctor says and just let it go or should I go to my hospital and see what they say? Thanks for any advice in advance.
