have been charting for a couple of months now and seem to have textbook perfect charts and cycles
.
this month i had +ve OPKs on day 13 and 14, my temp rose nicely above the cover line day 16 and went up steeply day 17 and stayed about the same very high temp on day 18. Today, day 19 my temp had reduced steeply and was exactly ON the cover line....
does this mean anything?
It isnt lower but i though it remained at least a bit above cover line until just before AF. 
just a little confused and wondered if it means anything?
