Greetings. Do not be worried. First see a qualified dermatologist near you at the earliest. This could just be melanonychia which is a common kind of pigmentation of nail and this can occur normally in Asian and African races. So first see a qualified dermatologist. Just in case If there's anything suspicious - your dermatologist may ask for a biopsy. Hope this helps. Warm regards, Dr Govind Suresh Mittal, Bengaluru.
