cycle changes

Tashawnda

So according to the calendar, I was suppose to start my cycle on the 15th of this Month....I started cramping anout 2 days before the 15th and staryed my cycle on yesterday...very light for a few hours and now there's nothing, but I'm still cramping. My cycle use to be very irregular years ago but since then I have had regular cycles....I feel like I may be going through menopause....Is that possible at my age(41)
