Scared and not sure what to do

I'm 31 weeks 5 days today. Last night me and hubby decided to split up. I haven't stopped having Braxton hicks and every now and then I feel like I'm having a contraction. I can't sleep my stomach hurts and I'm scared of baby coming to soon. Should I wait for my appointment on tuesday? Should I go to the hospital? I have nothing for this baby since hubby isn't working and was just about to get a car seat and crib when hubby wanted to call it off. Sorry if it seems more of a vent or rant but I need advice. I'm so scared and upset and idk what to do.
