Etonogestrel
"I am 30. My usual period prior to Implanon was like clockwork. I haven't got pregnant since the insertion. But I haven't stopped bleeding much! I stop bleeding 1 week each month.  Husband & have sex during the no-bleed week. So is it the Implanon's effectiveness? or that my husband & I are rarely having sex due to constant bleeding & my loss of sex drive?  Since the insertion I’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 & 11 months on I’m considering other options. I’m happy I tried it, such a high efficacy rating & no user error. It's worth a try & if it works for you, great!  But beware it might not too."
