I have been on the implant for 3 years. When to family planning to have it removed. The previous week I had a period which was quite heavy. The day I had my first injection after having it done I come on again but only for about two days. Since having the injection I have had some side effects. Pain in my belly , mood swings, feeling sick , going off food and Then not being able to get enough in my mouth , back pain, leg pain ... This has been over the course of 4 weeks I did not have a reaction as soon as the injection went in . Anybody gone through the same ? Or going through it now :-/ thank you :-)
