Where the hell is my period !

7 days late

Took a pregnancy test, negative . ( thank god, I can’t handle another one rn I already have a 2y old and a 8m old )

Removed my birth control 3 months ago

Got my 1st period ( after 2nd baby ) last month ( June 28-29ish )

Now it’s August 5th and no sign of my period.

I obviously know I’m not pregnant.

So what’s going on?

Are my hormones just messed up because of birth control removal?
