Was your following PP AF's different then the ones before you had baby?
Before J.J, my PP AF's were super painful, but spot on at 28-30 days.
Now, they are not painful (not complaining there) but they are SHORT as can be! I am only having a 7-8 day LP!
Granted, this means nothing to me since DH can't knock me up anyway, but do you know how super annoying it is to have your AF every 23 days?!!
