Stomach bug or morning sickness?

I'm 11 weeks pregnant and had horrible nausea between weeks 6-9 but never threw up. After week 9 I felt like a whole new person and back to myself. Last night I started throwing up in the middle of the night as well as all this morning. Now I just feel extreamly nauseous, have horrible body aches and food doesn't sound good at all. Do you think my morning sickness is back and worse or this is a stomach bug? My temp is 99.9. Thank u ladies!
