it is for mine. it seems like everything has went crazy inside my body. that's the easiest way to describe it.
At 47, the commonest reason for a period being off its usual schedule is perimenopause - the window of time around menopause. The easiest way to test for that is to ask your doctor to get a blood test for FSH or follicle stimulating hormone. This hormone will rise as the ovary becomes more resistant to making a follicle (the sac that contains an egg). Changes often occur with the periods getting lighter, then closer, then further apart. But this is far from true for everyone. These changes may occur over a number of years. They are very common.
