How often to replace: 1  Mascara: every 3-6 months (which means youâll have to throw it away before itâs used upâ¦ the same goes for a lot of these products, probably) 2  Eye shadow: every 6 months. 3  Eyeliner (liquid): every 3-4 months. 4  Eyeliner (pencil): every 6-12 months.
Blood Loss and Clots. Though it can vary from month to month, periods usually start off with a light flow, get heavier, then taper off. On average, women lose about 2 to 4 tablespoons of blood during each period. In terms of pads or tampons, that means changing them out every 2 hours or more. If you need to change out less than every 2 hours -- or have quarter-size or larger clots -- let your doctor know. Small clots of blood are common.
