It really doesn't look like you've O'd yet, but maybe your body was gearing up for it? Sometimes it does, and then for whatever reason, it just doesn't happen right then. Normal. Happens to lots of women.
I just wanted to let you know that I just ended a
78 day anovulatory cycle. But I DO ovulate. If that had been my first cycle charting I might have given up hope! I'm lucky that I started before that nasty cycle, and I knew when I was going through it all, that particular cycle was just one of those random annoying things. There's nothing wrong with me. I've never experienced anything like it before, and I bet it'll be a long while (if ever) before I have another. Just because you haven't ovulated yet, doesn't mean you don't.
I've never tried green tea personally, but I'm willing to bet actually drinking it would be of more benefit than tablets.
Keep up hope. In all likelihood you do ovulate, and really, at CD 22 it's too early to throw in the towel and call yourself broken.
