Advice and moral support please 😓

I have had lots of symptoms; sore boobs, cramping through the last two weeks, CP seems high and CM creamy. My AF is due today and my cycle is like clockwork. I did the silly thing of getting my hopes up but today my CM has a pinky tint to it which I'm assuming is the oncoming AF. Has anyone else had symptoms like these but still gets a BFN? I Carrie out a PT yesterday but it looked like a BFN. 😞
