"i&#039;ve been on sprintec for two years. before going on birth control when i was in high school, my periods kept getting longer and longer, eventually becoming 18 days long.  sprintec reduced my periods to exactly 7 days, i never had spotting in between my periods. before birth control i generally had clear skin and i still do for the most part.  i experienced no weight fluctuation. but in the past year i have noticed an increased soreness in my vagina walls over time, it started to make it unbearable to use tampons on my period at some points, so i will be switching pills soon."
