You really cant answer it exactly, but nausea doesnt mean you have a stomach bug always you know. I get nausea all the time for no reason at all and it lasts ages but im never sick and i never end up with a bug. Thank God!
All the advice i can give is that you should stick to eating little as possible for 2-3 days but dont starve yourself cause that causes bad nausea! And then you will starve the bug if you do have one and you wont have it anymore! drink plenty of water!
