1. First of all, do you mean you tested Dec 3? And that would be too soon. You need to test on or after your expected period.
2. Not to be rude but Meaghan Smith is completely wrong! First of a blood test is way more accurate than an at home test and with new technology you can take an at home test 1 week before your missed period. So the answer to your question is yes, you can trust your blood test. a blood test can detect pregnancy as early as 48 hours. so dont worry if it came back negative then your not pregnant
3. Lena...You are the one that is wrong. Hcg levels do NOT start producing until 4-10 days after sex. The earliest a doctor will give you an accurate result is about 6-8 days after sex. IT IS THE LAW! you got your blood test 6 days after, so it should be very accurate especially considering you haven't missed a period. I would not worry, women can have bleeding during pregnancy but they cannot have their ''period''.
