No large amounts of excercise
Not much stress, i've been fairly happy and not under any pressure, seeing as theres No school
I never usually have irregular periods

Well
What should i do? Any idea whats wrong?

At 14, your body is still changing and growing. When I first started my period, it was over a year before I was able to start calculating accurately; one month it was 15 days apart, the next it was 31 days apart.

It could be a sign of something more serious, but you're still very young and not fully developed yet.
