Hi, I Had A Question About The Nexplanon Birth Control..

hi, I had a question about the nexplanon birth control.. I have been sexually active prior to being placed on this method and during. I keep on having symptoms of pregnancy, and pushing it aside, though it is a topic I am continually thinking about. My breasts have become larger, and have recently started discharging a white fluid. I have gained a lot of weight, and my back is continuously hurting. my lower abdomen is always feeling pressure, making me constantly feel as if I have to urinate.. is it possible for me to currently be pregnant? I haven't had my cycle since before the nexplanon method was inserted, and its been a couple months since then...
