A contraceptive implant is a small flexible device that is placed under the skin in the arm area. Usually, the implant is placed in the lower part of the forearm, about 3-5 cm above the elbow. The contraceptive implant should be placed properly under the skin to ensure its effectiveness and safety. Placing the implant too deeply can actually lead to difficulties in removing it or reduce the contraceptive effectiveness. However, if you can feel it by your fingers - it should be fine. The insertion of a contraceptive implant is a medical procedure that should be carried out by a qualified doctor. He carefully evaluates the patient's anatomy and decides exactly where to place the implant so that it is effective and safe. In your situation, it was certainly similar if the implant was installed by a specialist - based on his experience and your physique, he placed the implant where it was indicated. In my opinion, there is no reason to worry, but if you have doubts - please consult the doctor who was responsible for the procedure, he will certainly dispel your fears.
