As pregnancy tests, quantitative blood tests and the most sensitive urine tests usually detect hCG between 6 and 12 days after ovulation. However, it must be taken into account that total hCG levels may vary in a very wide range within the first 4 weeks of gestation, leading to false results during this period.
HCG is in your system for 10 days. I have been told by more than one RE that you can test anytime after day 12 and it should be accurate. Take that with a grain of salt.
