Yeah, if I hadn't been charting my first few post-partum cycles I would have been absolutely convinced I was pregnant. My pre-pregnancy cycles were 29-30 days like clockwork, so when I got to CD38 on my first PP cycle I would have been pretty confused and disappointed if I hadn't known when I O'd.
It really is a double edged sword. Like Nikki said, I'd love to not have my mood for the day dictated by my temp/CM....but I don't even know how to stop!

I really do think I might take a break in June though. Just sort of a recharging of sorts. It's not like charting and trying everything in the world is getting me pregnant

So, if we take a more relaxed approach, what's the worst thing that could happen? Not getting pregnant? Big deal. I'm used to that...
Oh, and if we ever reach the point of needing to avoid pregnancy (not likely to happen at the rate we are going, we wanted a big family and wouldn't mind closely spaced kids), we would use charting to avoid. I would never risk using hormonal birth control.
