I have had implanon for about two years now and I didn't even think twice about the fact that haven't had a period in 3 months. But I have been unusually snappy lately and exhibiting some signs of pregnancy. Like sore breasts headaches hunger, excessive urination,fatigue, nausea, and my psoriasis had been flaring like crazy. I took a home pregnancy test and it came back negative. I have read that the implanon can give false negatives is that true and if so is it possible that I am pregnant
