Advice please

So I need a little advice, I haven’t felt baby move for a few hours now after drinking water and laying down pushing my belly trying to get her to budge, nothing...

Problem I’m having is I have no one to take me in if I were to call and they wanted me to, my fiancé works for the railroad and he isn’t allowed his phone. I have an appointment tomorrow at 2:30 but if something wrong I don’t want to wait that long.. I’ll also be 38 weeks tomorrow and I’m getting pretty nervous. I have four other kids at home with me and no money for a taxi, is there any other things I can try to get her to move around?!
