I had a contraceptive implant fitted 15months ago, i have not had a period since it being fitted untill the last couple of months were i have been bleeding for over a week at a time and very irregularly its also bright red in colour which is not normal for me when i did have period,. Im getting pains in my side and at the front, Also makes me feel a bit sick. Is this normal for the implant to make this happen or is there something going wrong with it?
