Contraction pains?

Ok so FTM here and so very confused! I have been having some random pains and the belly tightens every now and then. Some of the pains make me have to walk around but nothing that has made me think ok this is definitely it. My doctors always tell me when they are 5 minutes apart to call but my question is do I count the times the belly gets hard and I have no pain or just the ones that are painful? I feel like an idiot calling L&D; so if anyone may know I’d be really appreciative!
