Hello, basically I had an implant for 3 years, and didn't have any problems with it, now I've had it replaced, I've bad it 4 weeks now and in the last 4 days I've been having a dark brown discharge with the odd blood clot in it, is this normal? I never had this with my last one? I'm a little worried I may be pregnant because I read something about implantation bleading as a sign of early pregnancy, I don't know if it's me being paranoid but since the spotting started I've been feeling really sickly and off my food but I haven't been sick, I don't know if I have a bit of a bug as we'll but the both things together are a little worrying! I'm 20 by the way.
