So, it's not really essential that I know this, but I'm curious about the answer. 
FF says I'm either 20 DPO or 27 DPO, depending on which setting I put it on. However, all settings detect ovulation at some point in my cycle. 
I had a negative blood pregnancy test a few days ago, and I haven't started my period yet. (Though it should be noted that I've been on Provera for 3 days now.) 
The nurse practitioner at my RE office said it was possible I had a weak ovulation.  My question is, wouldn't I have started AF by now if I had ovulated at all? Would weak ovulation keep you from beginning a new cycle? Can I definitively say that I didn't ovulate this cycle? 
Results from CD 45, in case it's relevant:
Ultrasound: No definitive signs of ovulation (either that just occurred or were about to occur) 
Estrogen: 21
Progesterone: 1.05
I realize that the numbers probably don't mean much on a random cycle day with no baseline.

Re: Question: Weak ovulation or anovulation?
I'm guessing you didn't ovulate at all. If you just ignore the temps at CD16-26 it looks a lot more likely that you didn't ovulate because the temps at the beginning of your cycle and now are pretty much the same.
My vote goes to anovulatory.
@EllyD14 Yeah, the lack of period is really making me think I must not have ovulated. That would totally make charting almost useless (for my body) in my mind. I think my chart looks fairly ovulation. How I am supposed to trust it if I don't know until "20 DPO" that I never actually ovulated?? I mean, I guess if I'm being monitored from now on it won't really matter, but it's crazy that even though I'm doing all of this (and I even used a fertility monitor), I still don't know what's going on.
Yeah, I've looked at your chart a LOT recently and I thought you ovulated. But given that you're now 20+ DPO and (even with a random draw) your progesterone was only 1, I'm thinking the only option is that I was wrong. And FF is just as confused.
I've had anovulatory cycles where my CHs got moved around a lot and then finally taken away completely. I don't know what's up with your chart. I wish I did. And as much as temping seems pointless given your current chart, hopefully that won't always be the case for you.
