"i got the implant in january of 2015,  i spotted and had a light/medium period every day for about two and a half months which of course sucked but i thought it would stop once the implant &quot;kicked in&quot; and my body got used to it. i didn&#039;t have my period again until january 2016 they have been long, painful, and heavy. they last about 2-4 weeks and are irregular. sometimes there is a couple months between periods but others only a week. i have become moody, and emotional. also my arm is always painful and becoming numb and is covered in big blue veins. and i have cysts on my right ovary now that i have to get surgically removed. (not sure if that has to do with the implant) i haven&#039;t gotten pregnant. that is the only positive."
