What are my chances?

Kenna

So my period is 9 days late. I tested negative twice last week. I've been nauseous, dizzy, and fatigued getting more extreme symptoms each day. If I still don't get my period by tomorrow I will be 10 days late and am planning on taking another at home test either tomorrow or Friday. What do you all think are my chances of getting a positive test? I know it's sort of a crapshoot but I'm interested in hearing input.
