I am an 18-year-old female and have the implanon in my arm with a little over six months remaining on it. I have now been bleeding for 24 days straight, at first spotting a dark brown color, then went to bright red and became heavier only it was not the normal consistency; it was coming out like water. It began to slow so I m spotting like I was in the beginning. My breasts have become swollen and tender, I ve been having moderate cramping and severe lower left side back pain that comes and goes. I ve been extremely nauseous, I have a hard time finding anything that s not gross to eat and can smell things from long distances that make me want to puke (cheese and barbecue sauce) which used to be my favorite foods. I ve also had mood swings and heightened emotions. Example: Asked my fiance if he was going to come to bed with me since I had work in the early morning and he replied he wasn t tired and I began to cry. Is it possible I m pregnant or all just my birth control giving out?
