I have had my period for the two years Ive been on the implanon. (I get it removed next March.) This morning I had some pink on the toilet paper, now its brownish. Its not a lot, but I do have a two year old and the same thing happened when I got pregnant with him. I've take 3 pregnancy test today, all negative. With my last pregnancy, I took 6 that were negative before I got a Positive. Please help!
