Worried after doctor's appointment.

I was a nervous wreck while driving to my doctor's appointment today. Actually, I've been anxious for this appointment since last Wednesday, when I got my first BFP. I took a pregnancy test this morning, just to make sure the line was still there, and I got a very dark, bold line. This gave me a little bit of relief, but I was still nervous as I headed into the waiting room.

My appointment was at 10, and I got there at 9:40. Guess what time I was led back to the exam room? 10 fucking 40! It was past 11 by the time the Dr. showed up to examine me. WTF? Seriously, just make my appointment for a half hour later. My nervous brain did not need that extra hour to fret and twiddle my thumbs.

So anyways, the nurse had me take a urine test. I was a little concerned because I had been chugging water all morning, but it came back positive. Apparently, it was a faint positive. The Dr. seemed worried that it was faint. I told her that the one I took this morning was dark, and that I had been drinking a lot of water, but she still seemed concerned. Now I'm worried. I've spent the last two hours googling, and man it has not made me feel any better.

She also had me take a blood test to get my exact HCG levels, but I don't find out those results until tomorrow morning. I am dying. I seriously cannot concentrate on anything but those results. If they are above 400, I will be so happy. I am so nervous. I don't know what to expect or how I will handle another miscarriage. For reference, this is what pregnancy levels should be based on how far along you are:

I estimate I am around 5 weeks past LMP? I'm not sure, because of the miscarriage. Waiting is torture. I don't know what to do.
