Not necessarily hon. I'm not on the mini pill and bar one month, I wasn't after having DD1 either, and my CM ramped up to what I'd see in a normal cycle but I don't have AF yet (DD2 is 5 mths) and she didn't return until DD1 was 10 months old either.

Sounds like your body is returning to some sort of 'normal' though so be careful as a night of passion could lead to more than you bargained for! Well, the mini pill should stop that but you know what I mean

I hope AF continues to stay away for you but when she returns is an individual thing for each woman and sadly breastfeeding doesn't always keep her at bay.
