Aww this is so sweet... You sound like such a caring girlfriend (and much braver than I would have been with my boyfriend)... Well done you - he's lucky to have you sounds to me if you were going to catch anything you would have by now. Norovirus and SV's usually have a time limit of two days on average so if it lasted three days for him it's more likely to be FP. I'm sure even if you did get anything your boy would be there for you as we all are on here too... But it's unlikely. Just keep busy and stick to your normal routine and before you know it the danger will have passed in a few days. Anxiety can really takes its toll in your stomach so don't read into how your physically feeling too much... Hope things settle soon. Sure they will. Stay brave, you can do it xx
