What's is up with my temps? I am taking temp within the same half hour every morning. Using digital OPK and got a solid smiley (surge) on cd 22 - Glow kept changing my fertile days and AF time. Even though my temps don't rise real high after O (I do have low progesterone), I can usually see a definitive increase. This time I am having little rises and little dips. Did I possibly my ovulate this month? Anyone experience anything similar?
