birth control
"I've used this for 2 years and have had no problems whatsoever. I previously had an arm implant and experienced spotting and weight gain that wouldn't stop. After taking Quasense I've lost weight, no spotting, light & short periods. I use retin a for acne so my skin has been unaffected. I'm not sure about water retention because I believe that has a lot to do with diet and I'm athletic so I stay hydrated on a daily basis. I experienced no nausea, headaches, psychological side effects.  And most importantly, no pregnancy."
