Are other's temps all over the place on clomid?

Falyn
I'm after some advice about temping, please! I did it for a few months at the start of the year but found it made me too obsessive with TTC, so I stopped.
I'm now on my third cycle of clomid so thought I'd start temping again to see if I can more closely predict ovulation as I don't use opk tests.
As you can see, my temps are all over the place. Does anyone else have this experience on clomid? The last two days I've temped slightly later than usual as I've slept in. I'm not sure if this is normal because I didn't chart temps on my first two clomid cycles. 
Any advice?
