11 DPO and testing (-)

EWCM on the 4th, had intercourse in the 5th, I've been abnormally tired, I've had nausea, and breast tenderness (I typically don't have before a cycle) headaches, I've noticed I can smell things better even though I'm actually quite stuffy... I've been pregnant 5 times previously this seems like I am but I'm getting a negative back ... I know I need to just wait a few days but it's kind of hard to do.... Am I missing something?
