Confused

Okay, I'm confused.  My temp raised to 98.34 today.  That's the highests it's been all cycle and the day before AF is due.  I've had red in the spotting, so supposedly if there is any red it's not ib. Nothing changed as far as sleeping conditions go, it's the same temp in here it's been.. I'm nervous, I feel like I already accepted that I was out and was ready to move on to the next cycle, and then my temp spikes... I don't know what to make of that!
