"i got nexplanon inserted 4 weeks after having my child (mid august) so i&#039;ve only been on it for 2 months but i&#039;m not sure how much longer i can take. after having my son i was loosing weight like crazy! i was and still am breastfeeding as well. i gained 25 pounds during my pregnancy and had lost 45 pounds by 4 weeks postpartum. i have now gained 15 pounds since starting nexplanon. i don&#039;t feel as though it has had any effect on my emotions other than my sex drive is lacking, but that could also be from the breast feeding. i also bleed every day the first month after insertion and am constantly feeling bloated. if i gain anymore weight i&#039;ll probably be calling to get it removed."
