"from september-december 2014 i was having unprotected sex with my partner. in january 2015 i got the implant. i bleed for weeks at a time or just on and off. after about 7 months everything had calmed down. i go about 3-5 months without a period. if i even get a period i spot for a few days like i&#039;m currently doing but sometimes it&#039;s heavier for a few days then some spotting. i personally love this birth control i just had how much more easily agitated i am and the mood swings that come with it. they tell you to give it about 6 months for your body to try to get used to it before you decide if it&#039;s for you or not. the implant is the only precaution my partner and i take since january 2015- up until present(6-28-2016) still no baby"
