My wife is 10 weeks 5 days pregnant. Last night she threw up, had diarrhea, and a severe headache in her right temple. Today those symptoms went away and we visited the OB for the first time. Then tonight the glands in her throat have become swollen, she is congested with a runny nose, and she has the on again off again chills. Overall she feels run down. She took her temperature a half hour ago and it was 99. We are worried she may be getting the flu. What symptoms should I look for that would trigger a visit to urgent care or the emergency room?

I would try to get to see the doctor as soon as possible just to be safe.
