I need some advice. My doc office is closed but I do have an apt in the morning but I'm freaked out and don't know if I should go to the hospital tonight.

I started working (doing books for a friend's company) today was my first official day and I was helping get the office back in order since the flood. sorting receipts, filing invoices, things like that. I stood and sat for the same amount of time and I took breaks. Everything was fine. I got home, got my kids off the bus, came inside and started to put on some comfy clothes. I started feeling a little dizzy. I sat down on my bed and it just got worse and worse. I've laid on my left side seeing if that will help but it doesn't. I cannot move my head without feeling dizzy and wanting to barf. Now my head hurts and my heart is pounding hard too. It's pounding so hard my phone and hand moves every time it beats. Idk what the deal is and I'm really nervous. The baby is moving and has been all day. Should I go to the hospital or wait till morning and tell my doc? TIA
