Coverline always similar temp?

[Jokerette]

Those who are charting have you noticed that your coverline is usually similar from month to month? Mine always seems to be about 97.3 but this month my temps are starting off way higher and I got positive OPK's 2 days ago and I'm having EWCM so I'm pretty sure I'm due to ovulate very soon. But, If you look at my chart overlay my coverline is going to be way higher than usual! Has this ever happened to anyone, or do you think my body was gearing up to ovulate but its not ready yet, or it will keep dropping and I'll ovulate later in the cycle.

Attached are my OPK's and my chart and chart overlay... notice the teal cycle starting Sept 5 is higher than normal.
