Woke up to extreme dizziness!

Emily • Married for over 2 years, TTC for over 1 year, 2 previous MMC, expecting my rainbow baby Sept. 2016! 💕
What could be causing this? My doctor doesn't open until 8:30am. I feel extremely hungover! I drank some orange juice in case it was low blood sugar but I puked it back up within minutes. Now I'm not nauseous but still dizzy! Horrible feeling! I'm 7w6d.
