"i am an 18 year old, sexually active female. i just wanted to start off saying that birth control will act differently to each body. after reading these reviews, i became afraid to get it since weight gain, acne, mood swings, etc. took over for many people. my experience, i got the nexplanon two days before i was supposed to get my period (04/21/15). the procedure didn&#039;t hurt, only a bit of pressure and discomfort. i did not get my period till 8 days later after getting it inserted (normal as the nexplanon does make bleeding irregular), but i had my period only for 4 days like i usually do. so far, i have had no side effects which i&#039;m grateful for. i really do like this as i do not have to worry about anything. :)"
