Help! Totally at a loss...

AF is now 4 days late with no signs of showing. I had AF type cramps for 3 days before I was suppose to get AF but I’ve only had a few twinging pains in my back and nothing else since. I’ve taken hpt a bunch of times and all BFN... my cycle is very normal. Always 28/29 days. Even when I was on the pill, I would get my period before I started the placebo pills.

I also have a lot of watery CM...

here is my chart below. Should I call my doctor? First month ttc and I’m like totally lost...
