This is a common scenario on the approach to the menopause. Many women find that they can go months without a period, then suddenly get one back, usually heavy.
As you approach the menopause your hormones don't always fall gracefully, and can go up and down, and stay static for a while. When you get a sudden rise this can often trigger a bleed.
You say your periods are light but if you notice any changes, such as more heavy periods, this can cause anaemia which in turn can cause fatigue, low mood, and sleep problems.
If you become concerned, it is best to get this checked out by your doctor as well.
