Could I be pregnant or not ??Please help me!!!

So I put on the nexplanon on April and I didn’t put it on the certain days your supposed to so that it works I right away. And well I missed my period on May and this months too i know missing your period can be normal while on the implant but I was felling different so I decided to take 2 pregnancy test I toke them 1 week separate and they both came out positive? I’m I pregnant or is it the implant that messed around with test?
