Reviewed by Brunilda Nazario, MD. May 2, 2012 -- Researchers say they've found a way to identify the father of a baby as early as the eighth week of pregnancy. The new method, reported in the New England Journal of Medicine, uses fetal DNA isolated from the mother's blood.
Doctors can use a blood test to determine pregnancy almost immediately. My friend was 1 week and like 2 or 3 days and it showed in a blood test.

Some at home pregnancy tests can give results up to 5 days before your missed period but they aren't 100% accurate and give alot of false negatives.
