Need some Expert Charts Help please

[buckycat]

I think I'm 17 DPO but I can't tell at all. I went on vacation for a few days and didn't record any temps for those days.
For the last several days, by bbts have been high/increasing. I took a HPT yesterday (4 days after my expected period) and it was negative.
So now I have no idea if I am REALLY late this month and am O'ing now--or if it's something else.
Can anyone help?

Here is the same chart with the cross-hairs. Might be easier to be unbiased.
I also decreased the value of that spike-- I don't know if that was real or not because I was pretty sleep deprived that night.

sorry-- THis is the one without crosshairs and with that spike disgarded..

Here is the same chart with the temps with tmeps that were taken at a different than my usual time discarded.

I know, I seem pretty obsessive right now :-S It's so frustrating!

I'm wondering if you Oed on CD35. Your temps on CD34 and 35 are lower than your pre O temps. Many other temps are in the lower range too. So you may only be 6 DPO
