Blood Test Can Tell Fetus's Sex at Just 7 Weeks. A simple blood test can determine a baby's gender as early as seven weeks into pregnancy, a new study says â far earlier and far less invasive than other options.
The main advantage is that clinical blood tests for pregnancy can be performed just 7 days after ovulation, which would be a week before your next period is due. A urine test on the other hand is ideally conducted after the first day of a missed period or about 2 weeks after conception.
