Pregnant or flu?

I woke up feeling fine. But now as the afternoon rolls in I went to eat Mac and cheese and chicken nuggets with my S/O and the girls , I ate one nugget and a bite of Mac n cheese and started sweating and got really super nauseous . Had to run to the bathroom . Did not vomit but now that I stopped eating I feel better . My period is due soon too , usually I start getting really moody around this time but I haven’t been moody at all .
