"the first 3 months i had a period every 14 days.  they lasted about 5 days, slightly heavier bleeding than normal for me.  then after the 3rd month, my periods went back to their normal 28 day off, 6 day periods.    i&#039;m breastfeeding my 7 month old, so this is a great option.  no weight gain, no mood swings, no soreness or anything negative."
