Not trying yo scare you but you might be a male! It's not normal! But if you wanna stay a woman don't go to the doctor!

Oh...HELLO!!!!!!!!

Go see your gyny

I'm 22 and I have PCOS and only have about one period a year so you could have that, look it up... Or you could have a different hormonal condition, or in the very worst case you could have premature menopause.

Go to your doctor.

Not normal but I can't help but be envious. Call ur gyno - surprised u haven't already.

...Go see a doctor immediately
