No. I suppose I could but my temps are bottoming out again and there is no way they would be this low if I was pregnant. This is the main reason I chart. I started even before TTC because I had no clue and would be freaked out all the time by a late AF. Just imagine this kind of cycle while 20 in college! BC at least made it closer but I would still test before starting a new pack occasionally and have AF show up a few days later. My body may be a little screwy but at least I do O eventually.
Yeah that would be hard. I couldn't imagine such long cycles, whatever is up with my screwy body and not getting pregnant I have always had regular cycles and always O around CD 15 (apart from one screwy cycle in May) .
