No period for 6 days!!!

I’m late on my period by 6 days!!! They are usually really really heavy and I get really bad cramping!!! Absolutely nothing this month!

When I went to the toilet this morning this was on the tissue?

If this is the first day of my period it’s never ever been this light and such a little amount!

There is nothing coming out of me either, only when I wipe!!!

Is this the start of my period or something to worry about?
