You did the right thing by marking it inaccurate, or using the temp corrector. It is important to only temp after 3 hrs of unbroken sleep and at the same time each day.
However, I temp'd for a year and half, my temping time was 7am, but on the weekends I would sleep in and temp later without the temp corrector
Best advice woul dbe to see hwat your temp is like tmor. And perhaps BD just incase!!
