Temping Question: Do your temps follow the same pattern every cycle?

For example, if you have a slow rise, is it always a slow rise? Or always a fairly consistent low temp jumping to a fairly consistent post-o temp?

I'm on my third month of temping and even though my cycles are pretty regular, I'm not seeing a consistent pattern of temps. I temp every morning at 5:30, and I typically go to bed between 9:30 and 10:30 pm (even on weekends... hubby and I are such old farts :P )
