Thanks yeah I did get hot last night and had weird dreams that made me wake up feeling tired. Thanks:)
CD4 would have been too early for ovulation. The egg would not have enough time to grow and mature in just four days. It's not uncommon, though, to have a random high or low temperature in your cycle. It could just be a totally random spike, or it could be caused by a low-grade fever, a warmer-than-normal room, restless sleep, etc. Also, some women have irratic temperatures while on their period and won't see a real trend until after they're done bleeding. So don't worry, you didn't miss O :-)
Good luck this month!
