"i have had this implant in for a little over a year now and it was the worst descision i have made regarding birth control. after i had it put in, my body acted the same way before the implant. after about 3 months i had gained 10 pounds after not gaining any weight at all before the procedure. now i have un predictable periods that can last from 3 days to 3 weeks with almost no break in between. there can be heavy bleeding at times or just some spotting. i waited to see if the side effects would become less of a problem over time like the doctor said but they have not so i will be getting nexplanon removed."
