"so i decide to get implanon after using the pill and getting pregnant while taking it. after i had my son in 2008 i had implanon inserted. in the beginning i had terrible terrible mood swings. i was always angry and impatient, and i thought this would pass. i still get the mood swings but not as often. so i can&#039;t say if i am just crazy or if it is the implanon. the reason why i am not a big fan of this is because when i got pregnant with my first child i weighed 170 pounds i gained 12 pounds during pregnancy and dropped it almost immediately. got pregnant again gained 19 pounds, lost 9 pounds by the time got the implanon put in. i am now a lovely 202 pounds, so on average using this product i have gained about 11 pounds a year."
