AF late and breastfeeding

Okay, maybe this has happened to other mommas. My youngest is 5 months old, he is EBF and when he was about 3.5 months old, AF showed her fat ugly face... so she was due 2 weeks ago and has yet to show. Is this normal? With my first, I EBF until he was 4 months old, which is when AF showed up, but it was regular after that...

and I took a test, so I know im not knocked up.

PP periods with breastfeeding are always out of whack!

I BF and I didn't have a period for the whole month of jan. I took three pregnancy tests and was starting to worry lol. I started my period today! yay.
