Natural???: A woman's menstrual cycle characteristics change naturally over her life time. You were probably irregular at the start of menses and you will likely be irregular at the end of menses. Before menopause, the cycles become closer together then farther apart and more irregular. Normal women also have changes based on weight, medications and health status. I hope this information helps.

Maybe okay: At 17, the communication between your pituitary gland that tells your ovaries what hormones to make is still maturing. It's possible that this is why your periods are irregular. It's also possible that extremes of weight such as too thin or too heavy can be a cause as well. Thyroid can also play a role. At some point, maybe by 18, if you're periods aren't regular, make an appt with gynecologist.
