Chemical pregnancy? Doctor thinks I need a D/C

So I just found out I'm pregnant about two weeks ago. Got blood work 4 times and my numbers are going up, but not doubling. So the doctor wants to wait 10 days to see if I miscarry and if I don't, he wants to do a D/C. My thing is what if they got it wrong? What if I'm not as far as they think? Has anyone had this happen to them? I have a gut feeling that I will carry this baby and it's not a chemical pregnancy, my numbers are going up at least. I could see if they are dropping, but they are not. I don't want to make a mistake, I feel like I want my body to do the talking and if I don't carry this baby, my body will pass the baby. They could have it totally wrong! Please share your experiences with me?!
