"i had my nexplanon placed in sept 2015, 6 weeks after having my daughter. i was told it was effective and it wouldn&#039;t effect my milk supply. they were right. my milk supply was strong for 10 months until i stopped due to my busy schedule. i felt fine until my mild supply dried up. i have spent the last 2 months trying to figure out why i feel so angry at the drop of a hat and why being around people makes me anxious. i have no sex drive and i have vaginal dryness which makes sex painful. it has been effective in pregnancy prevention, but so is abstinence. i can&#039;t even remember the last time i was romantic with my husband. i have an appointment soon to have it removed and hopefully i will feel normal again. convienence is not everything."
