Confused and irritated

This is day 32 of my cycle...no period. My cycles have been consistently 27 days. I tested 4 days after missed period which was negative (3 different brand tests, bc CB looked faint positive) I'm going to wait until Monday and test again if AF doesnt show but I'm just so confused that she hasn't come and upset because I got my hopes up when she was late and then let down with the negative tests.
