I would be more than willing to bet you ovulated late. And I wouldn't be surprised if your DD ends up being changed to a little later if you get a dating scan. Not that we don't want you around I swear!!!!
But breastfeeding can still make your cycles weird every once in a while. Or the length could have changed. The prolactin produced while breast feeding can throw a loop in your cycle.
