birth control
"Got the implant in October 2015 and just had it removed July 2016. Gained a total of 45 pounds. Also had acne, mood swings, irritability, no energy, and extremely tired. Irregular periods and prolonged periods as well. No wonder this is birth control - who wants to have sex? Couldn't wait to have this out! Will NEVER get it again and will not recommend it to anyone else either."
