Sneak peek test

Has anyone done this test at the 6 week mark? Last time I took it you had to be 8 or 9 weeks so I feel like 6 weeks is so early! I didn't even think fetal DNA was in maternal blood at that point but if anyone has taken it did you get boy or girl result? I have 4 girls and praying for a boy but of course another girl would be just as great of a blessing! The test has changed too, I had to prick my finger, now there is an arm contraption 🤣 I'm just curious if I should just wait until 8 weeks again!
