period after having a baby....

Rocio

Ok so I had my baby on 06/27/17, I got my first period on 08/08/2017 since I'm not breastfeeding. I was supposed to get it 2 days ago and I started getting all moody and some serious cramps but then nothing. I just wanted to know if that normal for it to be late? and if so how long does it take for it to get 'normal' again?
