Hello, I am a 21 year old female of about 5' 6 and roughly 130 lbs. Last week after falling asleep I awoke to severe dizziness and vomiting. This lasted for over 2 hours. I went to the hospital and spent the night for observation. Now today, just over a week later, the same symptoms occur out of nowhere while I am at work. Not quite as severe but they are lasting longer. I have been feeling like this for about 7 hours and have slept for about 3 hours this afternoon. I am expecting my second child as well so should I be worried about my unborn child's health over this as well and what steps should I take?
