Hmmm.. I can't remember exactly what your chart looked like before.
Didn't you have a possible chemical pregnancy last cycle? My only thought is that sometimes women have a short LP after a miscarriage, so that is a possibilty...
It's hard to say. It seems unlikely that you would have so much Eggwhite/Wet CM after Oing, but I am no expert. It does look like Oing on CD17 looks like a *possiblity, but to be honest CD25 still looks more likely to me. Wouldn't it be nice if we could have very clear/textbook charts all the time?

Best wishes to you on this next cycle!
