Chin hairs?!?!?

Hey y'all,
I'm 21 and I noticed about a year ago that I had a black hair sprouting from my chin (aka not peach fuzz). Ok. Fine. I tweezed it and called it a day. A few months later it grew back, and then again. Today I noticed I have 3 dark hairs on my chin. Does anyone have any experience with this and know if it is normal? I'm of middle eastern descent and I've had dark hairs on my belly button and nipples since puberty. I was tested for hirutism at my gyno and it came back negative. I know women get some facial hair as they grow older but I'm freaking 21 years old!!! Freaking out a little and would appreciate some feedback! Thanks!!
