In June if this year I had the Implanon put in about a week after having a miscarriage. I bled for a few weeks due to the miscarriage, but after that my periods were normal. Well in August I started my period and to this day (10/24/12) I am still on it! At first it was a brown color, then it went red. And I had no clotting or anything. Well on Sunday (10/21/12) I thought I had finally stopped bleeding so my boyfriend and I had sex. Come to find out I was still bleeding. A few hours after we had sex I started to get very sharp cramps which I have not had at all the whole time I have been on my period. I also noticed that I'm bleeding a light pink/orange color and its not as heavy. I noticed that I have to pee more and I'm constantly tired no matter how much sleep I get. Also I am very moody. My doctor told me that the Implanon is full proof, but I'm reading other wise. Also after he inserted it I was not able to move my arm or touch around it at all or I would get a sharp pinching feeling and I had a BLACK bruise around it for about two weeks. Also I'm pretty sure it is moving inside my arm because I check to make sure I can still feel it and its in a different spot almost every time I check. Also the hand of the arm that the implant is in goes numb. There will be times when I can't feel my fingers. Is that normal? And could I be pregnant?
