My name is Jamie I am 19 and just had a baby girl 5 months ago. I had normal periods after giving birth. I got the implanon birth control in November and had one more regular period. This month I was suppose to start Jan.17th it is now feb.2 and still no period. I have had cramping and brown stringy discharge but not near enough to call a period. I have had this discharge for about 1 week now. I have taken 2 pregnancy test, both came out negative. What is going on?
