Ughh, I don't know if this post is a vent, moan or I just need some advice. I am sooo frustrated at trying to figure out when I am ovulating, that I could run and scream through the streets like a mad woman!!!

I mean, I thought that I had it all figured out, and now this month I haven't seen any EWCM and its CD22!
When I first began TTC, I had my cycle back to normal, had little or no stress in my life... now I am dreading everything. I hate the day I ovulate, because it always means that within 2 weeks I will be depressed, frustrated and about to give up! I guess I am at my wits end and I think that I should stop being so technical about it all and just go with it. I have thought about not temping, doing any tests and just maybe go by cm alone. I know that I won't really know for sure if I o'd but maybe I just wouldn't feel so stressed about it. DH doesn't understand how frustrating it is for me.. like I tried to tell him.." Its not like I am fertile every day of the month..", I wish that were the case though.
I guess I wonder if I possibly could be having another anovulatory cycle.. and what things should I look for on my chart? I've pretty much prepared myself for AF's arrival, so I guess you could say I am already devestated and I haven't even o'd yet. I wonder how many anovulatory cycles is common? If I am having more than normal, could this be a sign of PCOS, or my thyroid problem??
Sorry for such the long post.. any advice would be appreciated.
Thanks
