I'm such an idiot!

I have charted and monitored every month to pin point my O day for 4 years! Then the first cycle we TTC, I decide I want to be all casual about it so BDing doesn't feel like some kind of weird science experiment, KWIM...so I stopped charting and using the monitor. Dumb, dumb, dumb idea for me, ugh!! Why did I do that!?
Well now I have no idea when/if I O'ed this month!! AHH! Every month I have very noticeable EWCM (TMI) which I assumed would help me determine when I O'ed even if I didn't do all the charting/monitoring, blah! Of course, this month I didn't see any...
We've been BD about every other day, so I'm hoping we caught the egg if there was an egg to catch! For now I'm counting today as my O day for this cycle, since CD23 is the latest I've ever O'ed in the past. Maybe I was too stressed and didn't O this month. Who knows, I'll definitely resume at least using the monitor the next cycle we TTC!
/Sorry that turned into a longer vent than I was anticipating!!
