Period after Pregnancy

So I am coming up to be 4 months PP and I still haven’t received a period yet after having my daughter, is this normal ? When do you actually get your period again ? And is this normal ? I’m a first time mom and when I look the answer up I get so many different ones so I figured I’d ask the ladies here cause you guys are more reliable then google lol.. so please tell me how long after having your child did you get your period ? I’m not breastfeeding with my daughter is formula fed
