How early can blood test detect pregnancy

I had my beta done yesterday and it was negative, so I started lupron last night. However, I am little concerned, as I mentioned it yesterday I was spotting yesterday and little today with light brown discharge. Today is my 23rd day of the cycle. I think my ovulation was Wendsay and I believe that if so the fertilization should have occured either on wendsday or thursday. A common misconception is that implantation occurs 7 days after conception, but the research findings showed that first appearance of pregnancy hormone, HCG, due to implantation occurred 6-12 days after ovulation, with 84% of the pregnancies implanting on days 8-10 after ovulation. My blood test was done between 7 and 6th day.
Question is that if I didn't get a positive pregnancy test, does that really rule out pregnanty. What if the implantation took longer than the average.

HCG should show up in on a blood test about 7- 8 days past ovulation.  Of course if you implanted later, it might show up later.  HCG however, should be in blood by the 10th day

I would think that would be too early for a blood test to be accurate.
