Should I or should I not

For the last couple days I have been feeling feel flu like symptoms which are nauseated dizzy breast soreness to the point that I cant touch them and extremely tiredi have been eating every hour an 1/2hours if I don't I feel worse than I did. I don't start my AF until the 12th or the 13th depending what my body decides. It's hard for me to get up for work than I am at work for the entire day and still feel like crap I try to not think about but it's so hard. I have a cut feeling that I am Plus I'm not only one that feels like this every day in my family should I take a pregnancy test or should I wait until my missed AF
