Advice AF

So my implant just expired but it is still in my arm. But to my knowledge, it should no longer be realeasing any kind of hormone that would protect me from pregnancy (its been 3 full years and i am 260lbs). I had one normal period for jan. Then had sex 2 days after it ended. I am 5 days late for my period for this month.

My question: can i get pregnant that fast after the implant expiring? Or is it possible to get pregnant 2 days after a period ends?

Thanks for any advice or helpful personal experience
