Longer cycles

When I was younger, my cycles were all messed up, basically I never knew when or if I was going to have a period. For the past couple years, however, my cycles have been exactly 32 days long. Well all of sudden, starting two cycles ago, they are now 70 days long. Does anyone know what's going on?
