Hi there. Well, it's always hard to say as this requires an examination by a doctor to know for sure but it sounds like a yeast infection. There may be some irritation or remnants of a period or spotting and that is tinging the discharge the color you are seeing and its thick, because it is yeast and the itching is a classic sign. If you've never been diagnosed with a yeast infection, doctors recommend being seen. So, I wouldn't be concerned that it is something to worry about but because it is uncomfortable, get it taken care of. good luck hon
