I wish I had been charting! 8 days late now.

My husband had his VR in November of 2016. I never got pregnant so after a while I gave up on keeping track of anything besides when my period started. Now my period is 8 days late and I had negative tests on the 4th and 6th days of my missed period. My cycle is pretty regular and the only other time it was late was by 6 days after a car accident, which was stressful. I have no stress going on now. I sure wish I had been chatting my temps and symptoms right about now.
