I have a few questions

What happens/what does it mean if your period starts super early?

Im only 14 and I have a very heavy period can anything be done about it?

Is it normal to have major cramps and get nauseous when you start your period?

Is it also normal to get hot and cold flashes, headaches, fatigue, and getting dizzy/blackening of the vision on an everyday basis?

How many years should it take till your period becomes regular?

What does it mean if my periods are around 16days apart?

Its kind of hard to track my period because it is under 22days apart some times is it normal for my age?
