Hi I've been on implanon for 26 months now and have not had any periods or spitting since the very start. This week I got my first period since having the implanon inserted and I really don't feel well as a result. I am fatigued, have really bad cramps, feel faint all the time and even feel nauseous at times, but it isn't very heavy. It's really taking a toll on me in work. Before having the implanon I never had problems with my period, even though they were quite heavy. I got the implanon purely as a contraceptive, not to control my periods, but it seems to be suddenly effecting me very badly. I was wondering if you could offer any insight into why this is suddenly happening and why the symptoms are so severe. Also, if I'm suddenly getting my period now should I be worried about the effectiveness of the contraception?
