Lol - as everyone knows, I'm new to charting (I know I've asked a ton of questions, bear with me)

I'm 6dpo and wondering...when do the post-o temps mean something? Do they continually go up when a bfp is coming? When do they typically drop before AF is coming? Are there some general guidelines I should be looking for? I know there can be an implantation drop around 7dpo right?

I'm driving myself crazy, I think. Sorry for the rambling.

FWIW, here's my chart as of today (I don't even know if that's useful yet lol)
