Well, I guessed I wouldn't last long and I was right!
The plan was to go off BC, start charting to figure out if/when my cycle was regulated, use other protection when DTD until May when we were going to start TTC after my 30th birthday trip to Paris.
I did fine charting through my period, but the day that I "would" have taken my next active pill had I still been on BC, I flipped out. The pressure just hit me like a ton of bricks. Waking up at the same time/recording correctly/using other protection/potential side effects of going off BC... it all became too much emotionally.
So I'm going to take DH's advice (for once). I'm going to stay on BC until just before we leave for Paris, then stop taking it and NTNC for a bit. I'll possibly start charging after a few months if nothing happens before then.
I feel I have to do it this way, if not for my own sanity, than definitely for my DH's.
