is that everyone asks you, "are you sure you're not pregnant?"
and when you say, "yeah, I'm sure," they just give you a funny look and say, "but are you really sure?"
and then you have to explain to them that while stomach flu feels exactly the same as pregnancy, pregnancy only causes massive amounts of vomit, not full on bowel explosions of the other kind.
and then people look at you funny because you were just talking about the subtle difference between vomit-flu and diarrhea flu?
and then you freak out inside because are you really sure that pregnancy doesn't cause diarrhea? Like, really, really sure? and you look around all frantic for someone to ask.
and then you go to the dollar store to buy a pregnancy test because you're too cheap to buy a real one. but when it's negative, you freak out again because, I mean, you only paid a dollar for it! how can you be sure it's accurate?!
that is the annoying thing about having stomach flu.
