"i got the nexplanon in january it&#039;s only been a little over a month now. they said it has to be put in while i was only period so i got it put in about day 3 of bleeding and stopped in two days. then started up a couple days later for only two days and i haven&#039;t had one since. no cramps no weight gain and no pregnancy so far. i use to take the pill but got pregnant twice while taking it like your suppose to. my dr told me after you&#039;re on the pill for so long your body does start to not work as well and i was on the highest dose so after having my daughter i got the implant. i love it no alarm everyday to take the pill no shots ever couple months no having to do anything after they put it in your arm it&#039;s good for three years. best bc i&#039;ve used"
