Question about the tww..

So, my peak ovulation day was the 18th of this month, which makes me a little over a week for my DPO. My question is AF is due Monday the 27th... Should I test tomorrow or Saturday the 1st? I guess I'm just confused due to the fact that I don't actually have 2 weeks from ovulation to AF.

Obviously, I'll test if I'm late but I've been testing since last Wednesday because it was "5 days before my expected period."

Whoa, sorry for the cluster fu*k of words.. Could I be anymore confusing??! lol. If anyone understands what I'm saying please comment below! Thanks!
