A couple of months I think with my first. It's not unusual for it to take a while to come back xx
With my first it also took 13w and I wasn't breast feeding :)
I exclusively breast fed my son and I didn’t have a period return till about his first birthday which is also totally normal! And then I fell pregnant with this September baby 2 months later x
Took 13 weeks for my period to come back but I am breast feeding him and I think this is quite quick for a period to come back when breastfeeding
