Frustrating.

I'm 10 days late for my period.. I've been feeling cramps the last few days, so I thought I'd test just to see.. But a BFN. I have already went to my doctor she said a number of things could be delaying my period.. but I told her I can't relax until I know for certain if I am pregnant or not. I have an appointment to get a blood test next week, so I'm hoping to get a final answer. I would absolutely love to be pregnant right now but I'd also like to see AF show up if I'm not pregnant. It's just really annoying being this late without an answer from either side of the options. Anybody else going through the same issue?!
