birth control
"I had my implant injected in June 2015 and its Sept 2015 so in fairly new at this. I will say that my arm bruised for a couple days after injected. I had to apply ice for a couple of days before my arm was 100% useful again. After 3 months I haven't had a period and haven't really had any spotting. I have noticed some weight gain.. About 3lbs. I plan to keep an eye out for the weight gain. No other symptoms."
