Irregular postpartum period??

So I started my period at 7 weeks post partum and it last 5 days. I was spotting a little bit before but I didn’t count that in the 5 days.

I’m now 13 weeks post partum and haven’t had another period ?? I spotted a few days ago but it wasn’t enough for a panty liner and went away within 2 days.

I’m breastfeeding, on the pill and sexually active.

Is this normal or like ?? Should I be concerned? Lol

I feel like I should know these things so I hate having to ask../: but nobody told me anything related to postpartum when I got discharged so I’ve been figuring things out by myself.

Thank you ladies in advance ❤️
