Chart help

So I'm new to these charts. I didn't start temping until O last month (confirmed with Opk), but I've been doing it since. I know very little about these charts and what they are supposed to look like, but I feel like I'm doing something wrong because my readings are all over the place and up and down.

I am temping first thing in the morning, before moving or doing anything but opening my eyes, and doing it with an alarm every day so its exactly at the same time.

The only thing I see that does look correct is that all of my readings are lower (pre O) than when I started testing last month (post O) so I know that's consistent.

Any input?
