Used to have straight hairline, now Widow's peak

I'm only 18, and just in the past few months noticed I have a new widow's peak.  My hairline used to go straight across though.  Does this mean my hair is receding?

Well, being that having a straight hairline, or a widows peak is actually a genetic trait, and is impossible for it to just change on its own, I say you probably are experiencing some hair loss. Maybe is something silly, like wearing your hair too tight, but it could be something else. I would check with my dermatologist.

Thanks!!
