Implant & pregnancy

So I’m not really scared but I do want to know my chances. I’m not trying right now however if it happens I can be ready. Anyways so I got my implant two weeks ago tmr and last Saturday I had sex 3 times with my SO and we were drunk and obviously I didn’t use a condom but it was my last day being fertile ( atleast that’s what <a href="">eve</a> says)

Do you think I even need to think about it?

My implant was in just over a week so I think I’m ok.

BUT!!!!! I was wondering has anyone gotten pregnant with using the implant?

And does it have stupid reactions?

Sorry for long post.
