"HCG is produced once the embryo has implanted.. Sperm and egg meet in the fallopian tube, then travel down the tube, that takes about 5-10 days then the embryo implants in the uterine lining and begins producing HCG. you can usually get a positive home test anywhere from 7-14 days after ovulation, but to avoid false negatives 14 days is recommended"
That's from Wiki Answers ... a HPT detects this hormone, which I'm sure you know. I've also read that once implentation happens and the HCG hormone is released, it can be detected in your blood 3 days afterwards, and then your uterus "dumps" the hormone (don't understand the dumping thing) the hormone into urine and then it can be detected through a HPT..that takes 7-10 days.
So if you have an idea of the possible conception date, that may help.
Our condom broke, so I know the date and I'm patiently waiting. But I want to go test soooooo bad.
