Confused and hopeful

At 10 and 11 DPO, I thought I was getting my period but it was oddly light. The next day, it stopped totally. I got my hopes up that it was IB and of course have been testing neurotically. My period should have started two days ago. Still nothing. Went to the doctor for an actual test (had hoped for blood but she put in for urine); just got a negative result. I know it’s still technically a bit early to test, but I don’t want to hold out false hope for too long. What should I do? My period is always pretty regular and has never been so short or light. 😕
