worried sick

Today my fiancé told me he's had "watery stool" & has been going to the bathroom frequently (sorry tmi) anyways!! The norovirus is going around like crazy & I am petrified of throwing up- my biggest fear. I am 6w 5d pregnant & about 2 hours ago I had the WORST cramps ever & I laid in the fetal position & ended up running to the bathroom & had the worst diarrhea & as it was happening another horrible cramp came along. After all of that I've been fine, no cramps nothing but I am so worried that there's something wrong with the baby or I'm going to have a miscarriage. I am in full blown panic mode & im unsure of what to do😢😢😢
