anyone tested positive for flu???

So I work in healthcare and I deal with sick patients all day. Today at the end of my shift I tested myself for flu because I have all the symptoms and it was positive for A. My obgyne is already gone for the day and I am freaking out. Is there anyone that's had this while pregnant? I'm almost 5 mo and I know the only thing I can take is Tylenol for now. But I got an Rx for tamiflu don't know if I should take or not.
