Stressed

* AP *💍 👨‍👩‍👦💙

I was due for my period on June 12th

I’m 6 months postpartum and since when I first got my period after giving birth my period has always been on time never late now I’m very late, took a pregnancy test and it was negative we also use protection took one just to make sure.

Could it just be stresss? This is maybe normal after having a baby?
