Still no period

Hi! I been freaking out because I haven't gotten my period or no symptoms that its coming at all this month. I usually come on in the teen of the month (the middle of the month) but nothing's happened as of yet . I'm trying not to get my hopes up just in case it does arrive .My boyfriend and I are trying for his first baby and my second. Should I take a pregnancy test or should I wait till this month is almost to a close? Oh FYI according to Glo I'm supposed to get my period tomorrow.
