Help?

21 years old.. Been ttc with my hubby for a year now! Well I'm 9 days late today & still gotten a negative test. I'm extremely moody- very mad about everything- and peeing non stop! Literally I can barely hold my pee in & I pee so much! (Weird for me) also, I'm exhausted. All signs point to it except the hpt.. What gives? Should I wait to test in another week? Ugh
