I'm not strong enough for this

I've been crying all morning. I tested positive 6 days ago (Saturday). It was extremely light but it was there. I got blood work Monday (4 days ago) and my HCG level was 14. I was worried about it so I spoke with my midwife and she told me that would be consistent with how far along she thought I was. She wants me to wait a week for blood work to make sure my levels really jumped. I don't know why but I instantly had a bad feeling about this pregnancy. I started having symptoms two or three days ago so I started thinking that MAYBE everything would be okay. This morning, I stupidly decided to take another test hoping that there would be dark lines that would reassure me... Nope. The lines are about as light if not lighter then the first test I took 6 days ago. I don't know what to do. I am so upset and worried. I don't feel like there is anyway I keep this pregnancy and I don't know how to handle it. All I have wanted is to be pregnant again and now this. I don't know what to do. I've only been pregnant once before and I carried her to full term without an issue until the very end. I'm just so upset.

They had me come into the hospital and run blood work. Now I'm sitting in the hospital parking lot sobbing. I'm not strong enough to handle this.
