Pregnant on implant??

So I got the implant fitted, up until I got it fitted I was using condoms. 4/5 days after having the implant fitted I had unprotected sex but he pulled out. About 6 days later I had bad cramps on my left side for an hour, I thought this might be a period coming but nothing did. I have missed when my period was meant to come and I know that’s common with the implant anyway but the doctor that fitted it told me to take a pregnancy test If I missed that period when I got it fitted. I’ve also had breakouts, been super emotional and had very sore boobs but I’ve put that down to the implant. Is it possible I could be pregnant?
