Birth Control
"This was the first birth control I have ever taken but I was on it for about 5 years. I had no complaints the entire time, normal period, my weight remained the same, no drastic or bad side effects. All of a sudden I got a random period 2 weeks after I had just had one. This period lasted about 2 weeks and was extremely heavy where I was bleeding through anything within 2 hours or less! I thought maybe it was because I missed a dosage but I had tests done for other things and I was completely fine but the bleeding would not stop until finally I discontinued using the pill and the bleeding stopped.  It was really weird but for the 5 years I was on this pill I really had no complaints whatsoever."
