"have had this for a little over a year. i had my period for probably two months when it was first inserted, although it was very light. at first i would go about a month without my period and then have a two week period, sometimes more. compared to how heavy my period was beforehand, it didn&#039;t bother me. then i didn&#039;t get my period for four months which started to scare me, making me wonder if i was pregnant. however, it was a nice break from the norm, and i was not pregnant. it does its job, but can be unpredictable period wise."
