I've got the implant in and have had it for about a year (put in place 3 months PP) and last week started taking the progesterone only pill as well, due to some erratic bleeding. Since I started the pill as well I've had serious horrendous moods, anger, crying, I feel so empty sometimes that I can't speak. Does this sound right? Could it be the sheer amount of hormone causing me to have such mood changes?
