beansbeans and Ezz,

The problem with temps when breastfeeding is that your temp must be taken at the same time every morning after at least four hours sleep in order to give an accurate picture. Perhaps this can still work for you because your babies are a fair bit older than mine, but although my baby usually wakes for the day at the same time, I very rarely get four hours straight. Temperature will tell you if you have ovulated.

I'm not sure about cm while breastfeeding, but as I said before I've had heaps lately but no peak so no ovulation. I would just count any day with any mucous as a fertile day, this is what the Billings Method recommends (which DH and I have used to avoid pregnancy). Mucous is a better indicator that you will be ovulating soon, but if you're like me it can happen for a looooong time without ovulation. And I've heard stories of women conceiving without any while nursing.

As far as I've heard, the longer your cycle takes to return, the more likely you are to ovulate before you get AF.
