Is BBT pointless?

[Salley]

I have unpredictable cycles anywhere from 25 days to 31 and I just started tracking my BBT to attempt giving me an additional advantage or at least a better understanding of my body. Last month I ovulated late and apparently this month was very early... Am I wasting my time tracking my temp with such an unpredictable pattern?

No, temping is one of the best ways to understand your body.
Maybe try using opks aswell ?

I do use cheapo opk's that's why I know I ovulated early this month.. Thanks!
