Missing periods: How many months until I should be worried?
It’s common for teenage periods to go missing. Many people experience this.
When it’s missing for longer than 3 months, it’s our body’s way of tapping us on the shoulder, letting us know that something is standing in the way of a period happening.
Why do periods go missing?
Periods happen because ovulation happens (ovulation occurs about 2 weeks before a period).
Ovulation is when one of your ovaries releases an egg.
The key is to find out the reason (the root cause) that ovulation has stopped.
– The teenage body is still getting used to making ovulation happen regularly
– Stress
– Restrictive eating
Typical menstrual cycle

How to get a missing period back
When encouraging periods to come back, it’s important to address the root cause of why they’re missing in the first place.

How do I find a period specialist?
is a question we get all the time, so we made a list:
Will the pill bring my period back?
However, the pill won’t bring on your period – it will only cause a bleed due to the hormones that are in some of the pills and not in others.
This bleed feels like a normal period and comes from the same place, but it’s not a true period. The reason it’s not is because the pill prevents ovulation – and remember, the entire reason your period is missing in the first place is because ovulation is missing.
The pill will only further prevent ovulation.
