What is happening?

Period was supposed to start 3/27.

CM has been think and creamy up until 3 days ago when it has been very heavy watery.

Today when I came from work, I had a tiny bit of pink when I wiped. But almost 8 hours later....nothing.

Is there still a chance I am pregnant? Will I need to wait until tomorrow to see if my period starts? Has this happened to anyone else?

My TWW has been very long this time around..
