"i&#039;ve been on this medication since i was 17. i&#039;m now 25 so roughly 8 years. i was off of it for a few months also. i&#039;ve never been pregnant or gained weight. they do cause sore breasts but it eventaully goes away. only take as they prescribed. i missed a few days once and took the pills all at one time. i did have pain and bleeding. but if taken regularly and correctly i&#039;ve  had a positive experience"
