35 weeks with stomach bug.

My 5 yr old son woke up puking Wednesday morning, then diahrea throughout day with a few more pukes in the morning. Last night, Thursday night, I went from feeling 100% to 0% in less than an hour. Took another bath, and puked when I got out followed by diahrea every hour with me napping in between. It's now 5 am and I have a few doctor appts this morning I would like to not miss, thanks to US. Ultrasound, nonstress test, and weekly obgyn. I should be symptom free by appt time, but I'm nervous since I know I'm tired and I'm afraid of getting anyone else sick. So be sure to sanitize up after leaving doctor's if you don't already.
