"i absolutely love this form of birth control. i had it inserted in july 2015. i bled a small bit in the beginning when my body was first getting used to it but it was nothing heavy. i haven&#039;t gained any weight. i&#039;m 5&#039;3 and weigh 102. i was actually hoping to gain weight but that didn&#039;t happen. i forget that i even have the implant in at times. it is now february and i haven&#039;t had a period since november (yay). i feel great and haven&#039;t had any mood swings. as far as the birth control side goes, i am currently in a long distance relationship so i haven&#039;t been able to see how affective it is. i&#039;m sure it works just fine since i haven&#039;t had any complications from it."
