Am I pregnant? Test turned positive

So Im on the arm implant and my boyfriend has came inside me every day for about 6 months and lately I've been having really sore breast and dark rings around them, but I didn't think I was pregnant because I was spotting (which is normal with the arm implant) but then now I feel nauseous all the time when I eat and im really emotional... 
So with my friends I took 2 tests. The first on has a slight very faint line on it and the second was negative completley. When I woke up... They were both positive. Like clearly positive... Im scared to tell my boyfriend and I'm going to get a real test from planned parenthood tomorrow but has this happened to anyone??
