"I am 18 years old and have been on this birth control (only birth control I&#039;ve ever taken) since January of 2015. My first few months were pretty good. I had mood swings of course, regular periods, very mild cramps and headaches (which I usually get every now and then with a period). But in march of 2015 I had a very light period, and haven&#039;t had one since. Yes, I&#039;m regularly sexually active, I&#039;ve have the same boyfriend for the past three years and we&#039;ve never used any protection until I got on the pill. I take my pill regularly everyday around the same time and yet, I&#039;ve still had no period. I took a pregency test and it came back negative, any suggestions on what may be going on? Are other females having this same problem?"
