Confused ? ?? Can someone help me ?

🎀Miajoy🎀 • Baby Everlee is here!!!
So I kinda already asked this but Don't think I understand the answers I got... so my fertile days were from November 8-14 and I'm due for my af on the 27th of November witch is next Wednesday . I'm trying to figure out how many (dpo) I am . I don't know whether I am supposed to count from the 8th witch is the first day or the 14th witch is the last day? Or am I completely off??? Sorry if this sounds stupid . ? I'm new!!!
