I ve been having a lot of discharge. Odorless, mostly white, sometimes clear. Today, a part of it had gray dots(2 dots to be exact). Little itching, very little. I have the skyla iud put in back in October 6, 2014. Haven t had a problem with the iud that I know of. But my period stopped back in May, the 2nd week. I haven t had any sign of blood since then. No spots, nothing at all. I ve been nauseous probably since May but pregnancy tests are negative. Is there anything I should be worried about?
