birth control
"I was on this pill for close to seven or eight months.  It was great at first, absolutely no side effects, until the last three months on it. I was bleeding for four weeks at a time with one week of no bleeding in between.  This was my only issue with this birth control.  I have been on three other birth controls before this one (stopped because they were discontinued) and have never had any problems with any of them which just shows that I am not prone to mood swings or break outs, cramps, etc., so this pill worked for me personally but may not work for just anyone."
