I think you are spotting because it "appears" that you have just ovulated on cd14.....the o pattern before that is 1) a lil too early and 2) the post o temps are the same as the pre-o temps kwim.....
Sometimes a woman can spot alot or a little during ovulation....take it as a sign of a good strong eggie popping on out...
And remember that spotting can be from checking your cervix, bd'ing, moving around ALOT , ovulation, very very rarely implantation(the percentage is like 2% that truly get it)....or many numbers of things
I say that you just ovulated but of course in my famous words wait a couple days to know for sure.....bd tonite just in case .....and good luck
