I would say that last cycle you ovulated on CD18 not the CD26 it is saying. This cycle you are very up and down. It's hard to tell if you are leading up to O. I would like to see your temp go up tomorrow and continue to go up as todays temp is your lowest.

Are you consistently temping at the same time? Are you temping as soon as you wake? No tossing and turning? Do you sleep with your mouth open? All these things affect your temps and could be causing the erratic rises and falls. Have you been sick at all? All these things could be a factor.

The thing that makes me think there is something else going on is the fact that your other charts aren't as erratic as this one. There must be something different your doing etc...
