Cycle Day 35! Period is 9 days late!!

So... I normally have a 26 day cycle. I got a negative hcg blood test when I was on cycle day 30 (4 days late). And negative urine tests too. I'm CD 35 now. Having light cramping and bloating like my period is going to start but still nothing! I wish it would just start so we can try again! Has anyone else had a similar experience?! WTF IS GOING ON?!

****Update: If anyone cares. My husband took me on a romantic weekend date and we left our two year old with her grandma. It was so nice to de-stress and have fun. And my period started. I was just too stressed before!****
