What should I do?! Is this labor?!

So last night my contractions started to get close all night about 5-10 mins apart. And died down a bit after I fell asleep. Now today they’re picking back up and so painful but 15 mins apart. But I’ve been lounging around laying down all day because they hurt and I feel like shit. Should I force myself to go for a walk and get this going faster or just take the rest?
