Hello everyone, I'm sort of a lurker here and haven't posted before. However, today with the arrival of AF (again!) I thought I'd post a question.
We've been TTC since late last year but as nothing has happened yet, I'm a bit concerned that it's to do with my irregular cycles. They range in length from 21 to 30 days, with no decipherable pattern to them.

My question is, what is the best way to find out when I'm ovulating? I check CM but have never done temps, and I find charting my periods to be useless as they never come at the same time each month anyway. I've even tried OPKs but they are proving useless as well, because I never know when I might be ovulating and therefore when to use them. HELP!
