I waited until I got my bleed back (13mths PP) before going on the mini pill. I was on it for more than a year and yes, had regular monthly bleeds. I suspect waiting until my cycle had reestablished helped out on that front, but I do hear many mixed results in terms of women bleeding while on it or not.

I was getting my bleed every 21 days though, which sucked. But I don't know if that was due to the mini pill or a new cycle length for me due to being post partum?
