How long after having a baby did you get your period?

So my son turned 3 months on the 22nd Of July he will be 4 months on the 22nd of this month and I still haven’t had my period, and I’m kinda nervous. I did bleed in May but it was light and only for a short time but ever since then I had no period

Also I don’t have birth control yet. How long after having a baby did you guys get your period?

Idk if this is normal or if I’m pregnant again 🤦🏻‍♀️ and I’m honestly super scared
