"i got nexplanon put in on august 8, 2013. two months after i had a baby boy. i had my period throughout my pregnancy &amp; this is the first birth control i have ever been on. i have also been breast feeding. i got my first period a week or two after i got it out in &amp; so far i&#039;ve only had two periods. the first one was heavy &amp; lasted ten days &amp; the second which was in october lasted almost a week &amp; was really light. i have some weight gain, a lot of mood swings, headaches every now &amp; then, &amp; sometimes my arm hurts around the insertion area. otherwise i enjoy being on it with all of these side effects i greatly recommend it to every new mom."
