"i got this medicine because i couldn&#039;t take the pill at the same time every day. i&#039;ve had unprotected sex with my boyfriend, so in that sense it works great! for my period it&#039;s different. i stopped taking my pill because for a few weeks before i got the insert, i didn&#039;t have my period for months before but not too far behind getting the insert i finally started! but now its been 2-3 weeks and i still haven&#039;t stopped. it slowed way down and got lighter and i&#039;d stop for a day or two but then it got heavier after that. also, my cramps are horrible now and my lower backs been in pain for about 2 weeks now. i&#039;m not sure if these are because of the nexplanon or because of something else."
