I am super confused right now...

AF is 1 week late and I have had signs that she is on her way but nothing is really eventuating. I have had the usual cramps etc and yesterday I had some light spotting but today there is still nothing. I still have the cramps etc. I have PCOS but the months when my period goes MIA I have no cramping etc. So this is wierd...

Any ideas would be appreciated!!
