"my first experience was in april of 2011 with the implant implanon. the first few months were the hardest. i was depressed for about six months &amp; had severe mood swings. i refused to take any medications such as antidepressants &amp; relied on my friends &amp; family for support. the first year i only got my period twice. second year just one time and my third year i didn&#039;t get one. i randomly get cramps but no period. i have also randomly experienced headaches, backaches, sore nipples, brownish discharge &amp; nausea. i am sexually active with my husband. we do not use protection (condoms) and let me tell you, it is very effective! i am going on my second year with nexplanon with a total of five years with this particular birth control."
