My big toe nail started to turn purple about 2 weeks ago, is it serious?

My big toe nail started to turn purple about 2 weeks ago but it’s just on the right side of my toe nail, no pain and it seems to be on the skin directly around the nail bed and looks as though it’s slightly over the cuticle, do you think it’s serious? I don’t remember hurting the toe itself
