Hi last month I put in an copper IUD... after that I been having some yellow discharge‚looks puss-like. Is that normal?? Anyway my first period is due after insertion. And its so light that it can't even flow in a pads I only see it when I wipe after urination. I see blood. I feel bloated like normal periods and its time for my period to come because I have a 28 day cycle. Is this normal??
