Could I be pregnant?

I removed my implant and got on b.c pills and was told to use extra protection for the first week. I didn’t listen tho 🤦🏽‍♀️ I was due for my period tho a few days after starting the pills and I did get it . But is it still possible for me to have gotten pregnant from that day I had sex ?

In case there is any confusion here’s the break down of what all happened. I removed the implant sept 4th. Started the b.c pills sept 6th and also had sex that day. Started period sept 10th.

UPDATE:

Yes I was pregnant... he is now 6 months old.

Had him in June 25th of 2020
