"i rate nexplanon a 10/10 for birth control. i had it put in april 2016 and had it taken out october 2016 and never got pregnant....but i never knew when i was going to start my period and it gradually kept getting longer and was lasting 3 weeks so i had it taken out. i know it works differently for everyone. i was happy not to get pregnant but couldn&#039;t wait to get it out bc i couldn&#039;t control my periods with it in my body... plus it causes emotional changes and i cried all of the time.  it has been out for 6 weeks and i haven&#039;t had a period."
