birth control
"Nuvaring is effective in pregnancy prevention. However, the side effects were bad. The first month was fine with only one bad side effect (diarrhea) and I wasn't too sure if it was even from my birth control that month. It was never listed as a side effect. When I got my period it was light and lasted only about 2 1/2days. 2-3 months side effects started to kick in, more abdominal cramps, normal discharge, extreme bloating very often, nausea, and headaches. Along with these I became extremely irritant/very grumpy, major loss in appetite, and when I did eat the diarrhea would hit (severely). Eventually I had horrible back pain, and became very depressed and negatively impacted on my life."
