So I got my BFP three days ago. I have taken a hpt every morning since and the line continues to get darker. I called the doctor and am about 3.5 weeks pregnant.

I'm going to get a blood test on Thursday for confirmation on pregnancy (bc I'm really paranoid).

Can a blood test determine whether a pregnancy is or will end in a chemical?

I've read 50% of women have a chemical the first time around. The anxiety is killing me!
