Stomach bug and pregnant!!

Well I just felt the worst last night about 2am woke up with nausea and headache it didnt feel right. As I started to wake up to eat something because I'm 8weeks pregnant and thought it was just nausea it sometimes strikes me at night, I ran to the toilet to throw up! After 10 min I had the urge to throw up again but luckily didnt have anything to throw up. I instantly took prenatal probiotics and thak goodness vomit stopped, because it felt like a chicken salad I had last night caused this! I was so scared for my baby!! Has anyone ever had this situation? What natural remedies helped?
