"every review i see on this birth control is horrible. i&#039;ve had it in for almost 5 maybe 6 months and its been great. i used to have a very heavy period.. now i&#039;ve only had 2 periods and they was so light all i had to wear was a panty liner. i don&#039;t understand why people say all these bad things? and about the weight gain that was my biggest concern. i weighed 117- 120 before the implant. i&#039;m 17 years old btw. now i weigh about 109 - 110. so i lost a good couple pounds. and about the mood changes. none from not really having a period anymore my mood has been fantastic. and my sex drive has gone way up because of the difference. i just took my big sis to go get the implant a week or so ago. getting it put in dose not hurt at all. its great!"
