No period after birth control

Jude

I recently got off birth control (2 months ago) after only taking it for a year. When I was on BC I would get my periods once every 4 weeks and before BC I would get my period regularly every two weeks. Now that I’ve been off, I haven’t gotten my period for the last two months. I took two pregnancy tests and they’re both negative.. did any of you experience this when you got off BC and can give me some insight?
