When should you be concerned?

If you notice that any of the above start wildly fluctuating, or have large variations, it might be worthwhile to see what might be driving it.

If your periods cause you severe discomfort and pain, or your menses are accompanied with discomfort across other bodily functions, it might help to check your hormone levels.
