6 weeks pregnant and the stomach flu help!

Arianna
So my family has been staying at grandfathers house and 4 out of 7 have gotten a stomach flu... Sudden Stomach aches, really bad throwing up and diarrhea they were out for the whole day. I am 6wk and scared I'm going to get it! Washing my hands like a crazy person. We have a long drive back tomorrow and crossing my fingers i don't get it! Don't want anything to happen with the pregnancy. Any words of advice?  My husband has it now and he's in the bathroom having aches and stuff just coming out of both ends. Sorry tmi. He's not sleeping in my room tonight to avoid it spreading.
