Can I be pregnant

Laquiona

Hey so I recently got off birth control at the beginning of December.. I was on my cycle at the time of me getting it removed. I have had sex since removing it however I don’t think I could have gotten pregnant that fast. But as of right now I am 12 days late of my cycle and every pregnancy test I take is negative.. do you think I still could be pregnant or my cycle is changed due to the removal of my birth control? Please help !
