i know this may not be what is happening in your case but check it out to see if it sounds like you.
I have low progesterone levels and low HCG levels in my pregnancies (I need suppliments to stay pregnant). I tested negative at doctors office every time when I have been pregnant. You can ask for a quantative pregnancy test. Usually the blood test is qualatitive (either positive or negative result) but it is only sensitive from 25 units or greater (depending on the lab testing of course). Which is only about as sensitive as the home pregnancy tests. The qualatitive blood tests checks your actual level of HCG - where anything over 5 units is usually considered pregnant. A few other conditions can also give a slightly raised HCG level. But knowing the exact level can help your doctor diagnose pregnancy or anything else. My levels do not hit 25 units until around 6 weeks of pregnancy... and I have usually known I was pregnant by blood test before I tested positive to HT's. Just a thought :)
It could be too early for you still. Wait a couple of days and try again.
Good Luck!
