Hi!
I have been on the mini-pill since DS was about 8 weeks old (since April last year) and I haven't noticed too many problems. I have yet to resume AF but I put part of this on the fact that DS is a boobie loving boy and still has frequent b/f as well as the pill. I feel it is effective, safe and allows for what little spontenaity is left when you have a new baby in the house! I hope that helps... I will be using the mini pill for at least another year and intend to use it as effective birth control in between each of our children.

Good luck...
