My chart is completely confusing me this cycle. My pre-O temps were abnormally high and it took until 6 DPO to finally get above what I calculated as my cover line. Then I had a .8 degree drop this morning at 7 DPO! This is the first cycle that hasn't pretty much followed a typical post-O rise pattern. Part of me is hoping it is an implantation drop but with my temps as weird as they are, I don't know what to think.? Any insight ladies?
