I have a moustache!!

Okay, so my upper lip hair has gotten significantly darker lately and it is starting to actually look like I have a moustache! Especially in flash photos but also sometimes in normal photos too. I was wondering what other girls do to deal with their upper lip disasters? I am 17 and at school without a job because I am in final year so I can't go for overly expensive options but I do get a bit of pocket money here and there...
