Went on the injection in 2005 and it was fab no problems at all apart from weight gain. Doctor told me I needed to swap onto a different contraceptive due to me being on this one 9 years. Due to me having high blood pressure they said best thing would be nexplanon. Been on nexplanon now for 6 weeks and I've been having such bad mood swings. There terrible one min im ok the next I feel asif I want to scream :( also having other weird side affects like feeling sick, stomach cramps and a weird taste in my mouth? anyone else had this before?
