^Hugs to you Sis...don't worry try ulet sa next cycle.
What I know thru reading, Nag-iiba iba ang ovulation day natin...for the past 3 months na minomonitor ko cycle ko, Ovulation came on CD14, CD16 and CD17, nadetermine ko na rin that my Lutheal Phase is around 13 days (actually constant na 13 days sya for the past two cycles). Knowing exactly when you ovulate, and the length of your LP will give you an idea when exactly AF is due. Minsan akala natin delayed tayo, yun pala late lang tayo nag ovulate.
