Hate taking PT

Hubby and I have just started TTC. We are older - I'm 34, 35 in October (yikes) and he just turned 43. It's been 3 months TTC and he has a daughter, this is #1 for me. Monday AF is scheduled and for the past two months I was reading every sign my body gave me and was let down each time AF came. For some reason I would still carry a little hope even if I got a BFN. This month I don't even want to take a test until I'm late. I hate the disappointment. Im trying not to look into my symptoms but really, nothing is out of the norm. This is harder than I thought. So, do you wait until you're late to test? I see a lot of early PT takers as well!
