Nexplanon oops!?

Aliccia

I just got my nexplanon removed after 1.5 years with it in. I got it out January 12,2018 and started my period the next day. My period was very dark and it ended yesterday (no bleeding today) so about 3 days. Anyways My hubby and I totally forgot we needed a condom and didn't even realize until we were chillin later. What are the chances I could be pregnant?
