No Period Any more, how common?

[4BADASS]

My girl is on the pill and never has a period any more.

She gets spots or a spot.
Its been about 3 months from her last real period but gets the spot every month.

How common is this? Is this normal? And she s not pregnant.

If she's concerned or just switched birth control pills, she should check in with her OB GYN.
