Contractions.

I’m 37w2d and I’m having some cramping that’s getting kind of intense. They started out like period cramps but the last one I had lasted a full minute and took my breath away. I keep thinking maybe it’s just that I need to use the bathroom but I’m having zero luck in that department. They’re coming like every 10-15 apart. My doctor wants me to call at every 7 minutes apart but I’m an hour away from the hospital. I’m scheduled for a c-section on the 11th as my doctor does not do vbacs. I’m just looking for any type of advice, do I call now? Wait it out? I’m not sure.
