Have you considered working with an instructor who can walk you through the process of charting, how to observe and interpret your CM, etc? There are also systems of charting that identify ovulation with CM only, so you don't have to worry about temps. There are teachers for those systems too.

I would encourage you to take an actual course, it won't be nearly as frustrating as trying to figure it out all on your own - especially if you have complicated cycles. (I know what that's like!)
