DS is almost 11 months & no sign of AF yet. Has anyone else TTC before AF arrived?

DS is only having 3 feeds a day & is not fed overnight (hasn't been for months now).

Not TTC just yet - but wondering if we will be able to when we are ready (hopefully when DS turns 1).

If AF doesn't return before you get PG, how do you know you are PG (apart from doing test)?? Also, does CM follow normal patterns when BF-ing (ie. is it still a predictor of ovulation)? Does the temp method still work for predicting ovulation - or does the BFing interfere with that?
