Negative and Negative

My average cycle is anywhere from 22 to 27 days. Today is cycle day 31 and I still haven't gotten my period. I took a couple of tests including one today and they were all negative. If I'm pregnant, I will be so happy. If I'm not, that's okay. That just means more time making a baby. The negative tests and no period is killing me though. I keep thinking I have to be pregnant, but then the test is negative again. Not even a faint line. Completely negative. I'm just frustrated.
