Falling at 38+3

I took my 1yo to the park today & as we were leaving & I was getting into the truck my sandle decided to twist around my foot & I lost my balance & fall. I was able to catch myself by grabbing the stirring wheel but it still jolted my body pretty good. I've been having contractions on & off since then, some only being 2-3min apart, & I've had alot of constant cramping. So far there is no blood or discharge but I'm still kinda concerned about my baby girl. I live an hour from the closest hospital & I ain't sure if I should go get checked out right now or wait it out & see how the night goes. Baby girl is scheduled for an induction this coming thursday.
