Girls I need your help!!

So lately I've had nausea, my boobs hurt like crazy and my lower back hurts so bad and I have a huge headache. I have irregular periods and my period was supposed to come the 10th but since I'm irregular I'm not sure if I should wait a little longer to take a test. I had unprotected sex the 23rd and I've been having unprotected sex since. How long should I wait to take a test? And if I am what would be a cute way to tell my husband?
