Help please :( labor?

I went to go lay in bed after severe cravings. I've been feeling "off" all day.. Then I'm laying there and I'm cramping on the side I'm laying on. Baby is rolling around as usual , but now the cramping is getting more irritating and uncomfortable .. At this point I can't move my legs and whenever I do move them it's excruciating and my pelvis feels like it's cracking and popping.. So I forced myself out of bed for fresh air outside and I'm still hurting a bit.. What could this be.. Hospital isn't an option since only hubby drives and our 10 month old is sleeping and it's 2am ..
