Confirmation appointment

I finally had my confirmation appointment today, but it was with a nurse and not a Dr. She had me come in and take a pregnancy test, and then ran 11 viles worth of blood work on me. She did all of my paper work and put me at about 9 weeks 5 days, then went back to check the test and had kind of a worried look on her face. Asked when I got positives, and that the positive was really light for being further along. They AREN'T checking my levels with blood work though, which confused me because with DD I had a blood test.

What can cause such a light line at almost 10 weeks? I don't get to actually see the OB until next week sometime. It kind of made things seem like they weren't going so well, but I don't know what else to think.

Idk what causes it, or if all women do it, but I'm just over 9 weeks and i still take home tests to ease my mind. My test lines are getting lighter, but baby is perfectly fine.

It's the hormone levels leveling out, I'm wanting to say.

I just notcied she said I'm 9 weeks 5 days, which the calculators put my due date around August 31st. She said my estimated due date is November 24, 2013...   FFS.
