pos opk no temp shift

[StranjeGirl]

This has never happened to me and I'm totally depressed as I was feeling good about this cycle and our timing. My opk turned positive sunday night and it was even stronger on monday morning. Also got a high on fertility monitor monday morning. By tuesday morning it was lightening again...still maybe positive, but lighter. Had achy ovaries on sunday and monday morning. Never felt true O pain, but some months it is more subtle. Expected temp shift today but instead it is lower and has been low all day. This has never happened before. My opk is negative but still has a lot of color to it. What does this mean? Did I really not O, and if not, will I O later?? I am so confused. We didn't bd last night as I thought I already O'd. Did we miss it now? If I am going to O later will I get another pos opk?? Here is my chart Thanks for any input!!
