"kept me from getting pregnant, but that was the only positive effect this medicine had on me. in a year i went from 120 pounds to 180lb, my face was always covered in acne, and i had ridiculous mood swings. right after i had the implant removed, i lost ten pounds and my skin began to clear up. while this is my personal experience, some girls i know with the implant have no issues with it. just be careful when choosing a birth control method."
