"i have had the nexplanon for two years and i love it. i started with period only every other month. for some time i did have two months in which i had a period almost two weeks of spotting, it stopped and then i got it again a week later. but that only happened once. i don&#039;t feel any mood swings other than what i would have before so its just my normal me. i did gain weight but it was about a year later and i doubt was due to the birth control because i can lose it when i want. i love this birth control it has worked great for me and i do recommend it. it is safe and easy."
