OPKs and BBT

So, ladies....

For those of you who use OPKs, when did you decide to use them? Did you use them right off the bat when you started TTC? Or wait a couple months? How helpful/stressful do you find them?

Annnd...same questions for taking your bbt. When did you start? Is it helpful, or does it make baby dancing more stressful?

I'm really good (like, SCARY good) at getting overly excited about something before it happens. The TWW is torture. If I sneeze wrong, I'm jumping on the "Maybe I'm Pregnant" wagon. Right now, I'm trying to decide if I should brave these options or wait a couple months before tracking using one or both methods. I don't want to set myself up for disappointment every month.

As a side note: we've only been trying for about two and a half months now.

Help?
