Growing hair on my chin at 22?

Can someone explain to me as to why I’m a 22 year old women & I have a cluster of chin hair that grows rapidly even after I shave it 🙄 I’m a dirty blonde so you can’t see it from far away but definitely up close if I’m not wearing a mask & I know it’s there! it grows out long enough it looks like I’m a pubescent boy who’s trying to grow a beard 🧔🏻 what do I do to make it go away or to stop growing so fast even?? I don’t have money right now for a waxing kit off of Amazon because I start working next Wednesday. But I think waxing might be the best option. What do y’all think?
