You are in the right age group for the start of the menopause, and one of the key pointers is when the cycle starts to go awry - periods missing or coming too soon.
So my guess is that you are starting the menopause. You can ask your doctor for a blood test to see if your hormone levels have fallen.
There's no real way of predicting how the menopause will go though - your periods may just be late for a while or never turn up again: it's a case of waiting and seeing!
