Should I be worried or is it okay?


I am 13 weeks pregnant with twins, so last night I had ground beef tacos. my husband ate the same thing and we were both fine. At 4am I woke up and felt a little discomfort, so went to the bathroom and threw up. It wasn't a lot and felt fine instantly. I was able to go back to bed with no problem. Should I be worried it was some type of food poisoning? my main fear is that something happens to the babies.
