menstrual disorders
"This was my first birth control and I used it for about five years before I had to switch to something because of insurance.  I experienced 1-2 days of light spotting when I first started it.  It eliminated all menstrual pain and cramping that I experienced before starting on a birth control pill.  It also made my periods start like clock work.  I did experience more pimples when I took it but nothing major.  I never experienced any weight gain on it.  This pill did pretty much kill my libido though."
