Why would your period stop if you're not pregnant? If im not pregnant, not on drugs, and still young, why haven't I had my period in six months? It's been worrying because before, it was on a normal schedule.

Get a check up.

1. If you haven't had your period in 6 months and haven't developed a baby bump by then, you are most likely not pregnant.
2. If you just had your first period not long ago, your period is probably just irregular. That's normal for girls beginning their periods.
3. If you are really worried, then get a check-up just to make sure you are okay.

There's a real possibility that your menstrual cycle has stopped because you are no longer able to have kids. I would advice getting a checkup.

If you have a lot of stress in your life it can through your hormones off balance and therefore delay your period. Its happened to me before but only for a couple of months. I would go to your doctor to have it checked out though. Hope everything is okay x

Malnourishment is a factor
