"i got my nexplanon in after my 1st son was born. never had a problem with it. didn&#039;t gain weight, didn&#039;t get a period for the whole 3 years i was on it. now that my second son was born jan 2015, i got it again in march 2015. once again i loved it. not a period in sight yet. this is the best for me because i don&#039;t have to remember to take a pill every day. no oops babies here."
