so in my hometown the county fair just started yesterday.. I went with my girlfriend and towards the end last night we both had 2 tacos (same meat) and shared a funnel cake. Well apparently in the middle of the night last about 5-6 hours after we ate she got really sick just one time. I didn't know until she told me this morning. Should I be worried that I'm going to be sick too?? She said it could just be because she ate a lot and then laid down right when she got home. But I've felt fine so far, and we ate the same food! She hasnt gotten sick since that one time and its been about 6 hours since then. She says she feels fine. Could it have been a bug or something? Is it ok to go about our regular day? I mean like should i avoid kissing her or anything of that sort? for how long? any help would be appreciated.

Thanks!
