question: I have the implanon implant for 2.5 years. I have had no bleeding what so ever until today, there s quite alot of blood & clots. I have stomach problems anyway, have had for a year & half. I also have 3 tiny ulcers . I just wanted to know whether it could be a period or not. I also feel dizzy & keep being sick, the sickness is normal since i had stomach pains.
