"my experience when you first got this birth control i did not get my menstrual period for about 2 1/2 years. now that i am toward the end i have been getting my period once a month and last about a week each time. now that i&#039;m about 1 months away from the birth control being taken out i am getting my menstrual period but this month seems to be lasting longer it&#039;s been two weeks now. so i am going to call my doctor to see why i am concerned but i have 2 1/2 months till i hit the 3 year of having this birth control."
