Breastfeeding and late period

PNW💚

I know some women dont get a period until after they stop but i havent been that lucky lol. Im currently 6 days late and dont know what to think, its driving me crazy.

How late have you ladies been if your period has returned and you are still breastfeeding?

Ive taken multiple test, all negative. I guess im mainly worried because i have gotten one period since giving birth and im not on birth control.
