I'm giving up!

I'm sorry but I need to vent , this is the most emotional process I've ever had to through. I'm 10 days late and ik sometimes it's too early to find out if your pregnant for some , and all my tests have come back negative ( urine and blood) at the doctors and all my HPTs have been negative. I'm so depressed and sad, I just want to know! Is that such a bad thing? I'm waking up crazy hungry and nauseous everymorning and it's making me more tired then I already am! I don't know if I can wait any longer. My OB says wait two more weeks and if AF doesn't show then they will run more tests.. TWO F***ING WEEKS??? SERIOUSLY?? At this point I'm throwing in the towel.. all my hope is gone :"(
