Hey Kim!

Head over to the article section on BB and go to conception and there is articles in there regarding how to check your cervical mucus (CM) and what to look for and what is fertile cm and what is non-fertile cm... i've read it many times over the last few months (still hasn't worked for me)

I would only start temping/charting once you're off the pill, as like Sarah said, when you're on the pill you're not really having a 'real' cycle hence your temps could be all over the place or not correct to your true cycle iykwim....
You'll probably be one of the lucky one's again and conceive #3 pretty soon...
Not long til you start trying... exciting! I hope you get your lil' prince.

I've been off the pill since March07 and only actively ttc since late Sept07 and i've gotten to know my cycle so well now it's amazing learning your body and cycle and patterns! Quite interesting... however even with all this knowledge it still hasn't helped me! But I think you're more fertile than me so you won't have a problem

btw - i am never going on the pill again!! I reckon i'd be UTD by now if i hadnt have gone on the pill!!!
