ttc #1 aged 31

It's our first month ttc. I had a m/c in December 2013 with my ex and my husband knows all about it.. I'm so excited for my rainbow baby. I'm currently in my first tww and AF is due in 9 days. I know we can do a clear blue early detection test in 4 days but as its our first month I don't know whether to just wait for AF and test if late rather than pre-empt potential disappointment so early in ttc. Arrgh!
