Im 50 yrs old. During y 4o's i experience pain during my period and it lasted around 5 days for rhat pain. I took ibuprofen to ease the pain. 2 mo. Ago i used sanitary napkin with ions. For this mo. I had my period last april  8 with light blood flow and become heavy last monday april 16 & up to now it does not stop yet but there is no pain. Im planning to see a doctor by monday coz im already worried of my condition even if im not feeling any pain. Is this a menopausal rection or effect of usig the sanitary napkin with ions? Tnx
