I have implanon birth control, have since April 2009 after I had my child. I Was supposed to have it removed in 2012, but never did. So it's 2 yrs old, is it still working? Or could I be pregnant? I haven't had a period in months, but they have always been irregular, My stomach looks bloated/ huge. When I press on it it's squishy to a point then very hard. I'm gaining some weight. My breasts are sore once in a while. I'm always tired. I've taken a few pregnancy tests, but they come out negative. I don't know what's wrong.
