My pretty chart isn't so pretty anymore

I was excited to temp this morning and hoping for it to go up again but it took a rather large nose dive. I have no idea what this means since I don't usually get AF until 12-14 day LP. So this is quite interesting. It may just be my shortest cycle ever. I also have cramping on my right side which feels much like O pain but that can't be right. I really getting sick of charting and I am for sure next cycle, stopping after I confirm O.
