birth control
"I received the implant around March 2016. The first few months my periods lasted 10 or more days. Each period was between light to moderate flow. After about 4 months it began to even out to 6 days each period. Before the implant I have had cramps and sever back pain with each delightful time of the month, before I had no problems with my cycle but now it is unpredictable. The implant hasn't improved the cramps and back pain but overall the effects of the implant is better than being pregnant. I am sexually active with one partner and with the implant I don't have to worry about getting pregnant."
