I've never charted or temped but I still considered myself actively TTC for my first two pregnancies: I counted the length of my cycles and paid attention to ovulation symptoms and tried to BD around those times. We wanted to get pregnant....NOW!!! lol
But right now I consider myself NTNP because were simply having unprotected sex. I do try to pay some attention to my cycles because they are irregular and I need to make sure I have a stock of tampons/pads ready so I'm not caught unawares. Also, I need to know when to test if necessary. But the main reasons is that I don't feel in as huge a rush to conceive. Af getting me still has hurt (and we just started) and I feel a twinge jealous when people I know get pregnant but deep down I'm very happy with my DS. I feel it will happen at the right time.
