"i&#039;ve had this for 1 year seems to be working good i&#039;m not pregnant. i used to get painful heavy periods all the time but since i&#039;ve started this bc i&#039;ve only had two very light periods that lasted 1-2weeks  both times the blood was brown like it was old or something. sometimes it feels like it itches or i get some pain if i lay on it the wrong way."
