Having a period so soon????

So I gave birth Oct 10 vaginal Delivery. (Speedy recovery) Spoke with my doctor at 6 wk Post Partum and since im breastfeeding she said could take up a year till i get my period. Then Yesterday I started to bleed and im sure its my period. It just sucks ass on top of taking care of my baby and having to deal with bleeding again and ahh feel all over the place.

Guess my question is. Has this happen to anyone else? Just want to check that this is normal.

Sorry just wanted to rant for a bit also***
