What should I do?! TTC baby #1

So AF was due today and so far nothing. I've been having nausea, no vomiting. A few cramps over the last couple of days and some lower back pain. And really strange dreams where I find out I'm pregnant. I have been off BC since Jan, but this is our first month TTC. My cycles are very regular and always arrive when glow predict. When do you think I should test?! I don't want to be dissapointed.
