Someone help😩

I have recently had the implant put in (Thursday) and I have just taken the bandage off and I'm very scared that my implant is in the wrong place. I know usually the implants are inserted on your inner arm, but mine seems to be on the inner/bottom of my arm, not actually on the inside. Also I tried to press and feel for it and I can't entirely feel it. I was wondering if anybody could help me with this, as I'm terrified it's been inserted in the wrong place and therefore will be ineffective!
