Val - I have insomnia on and off and I also have different waking times. I still temped every day and was pretty consistent that I temped after the same amount of time of sleep. Like everything else in this crazy TTC world everyone is different. It all depends on your metabolism. For me my temps weren't affected but others here their temp could be completely out of wack because of sleep. I agree to go ahead and start temping and figure out what your patterns are. You have nothing to lose.
Stormy- Have you tested??? Based on the last temp you entered it doesn't look like AF is anywhere near. Have you done the Qtip test yet? Check in when you can.
