I need advice

So, my period was due 6 days ago and 2 days ago I had cramps as though I was starting my period but they only lasted about an hour. Mind you I have PCOS so my periods are heavy and very painful. Not only was the fact that I was late weird, so was the short cramps. Then there wasn't any red or dark blood like usual there has only been light pink almost stretchy cm when I wipe. I haven't needed a tampon or pad and I am super confused. This morning there was nothing. Does anyone have any opinion on what this is????
