HELP!

Hi girls, I've not come on my period, was supposed to arrive yesterday. Checked my CM today and it's like school glue & my CP is really high like I can hardly reach it. Getting mild abdominal cramps and feel abit nauseous... Does anyone think this could be a sign of pregnancy? I've not had chance to take a test as I'm so busy in work (it's took me 4 hours to write this post hah) Tia x
