12pp and no period...

I'm not breastfeeding, we've used condoms everytime and I still haven't had a period, I had my postpartum bleeding and that only lasted about 3 weeks (pretty normal for me this is my 5th baby) but I've always started my period shortly after my pp bleeding like no more than 4 weeks and I still haven't started yet... I messaged my doctor but they can take up to 72 hrs to respond, ugh stressing me out, anyone else in the same boat? Pic of my sweet little guy because why not? :)
