I just turned 35 but for the past 6 cycles my period has lasted 13 days. The flow starts light..gets moderate for two-three days tappers off to a light (2 days) and then really ligbt (a thin pad) almost watery discharge for the rest of the time. The cycle length has been regular. I don't feel pain beyond the period cramps for the first few days. Is this normal? Am I entering perimenopause or is this something I should be concerned about?
