I've been on Micronor and EBF since six weeks too. No sign or dear old Auntie for me, either. We're down to four feeds a day. Ooh, I wonder if I should check with my doc as to whether another form of contraception is needed. I know my pack says that if taken correctly at the same time each day, the chances of getting pregnant are 1 in 200 (if taken at varying times of the day, it's 1 in 20). I'm pretty religious about it, and assume that the BF is an extra security measure.
