"i am 30. my usual period prior to implanon was like clockwork. i haven&#039;t got pregnant since the insertion. but i haven&#039;t stopped bleeding much! i stop bleeding 1 week each month.  husband &amp; have sex during the no-bleed week. so is it the implanon&#039;s effectiveness? or that my husband &amp; i are rarely having sex due to constant bleeding &amp; my loss of sex drive?  since the insertion i&rsquo;m emotional, sensitive, irritable, anxious, depressed - a constant state of pms. i have gained weight, 6 kg. the side effects are outweighing it for me &amp; 11 months on i&rsquo;m considering other options. i&rsquo;m happy i tried it, such a high efficacy rating &amp; no user error. it&#039;s worth a try &amp; if it works for you, great!  but beware it might not too."
