4D ultrasound or blood test to determine gender

Diana

I’m soooo freakin anxious to find out the gender of our growing baby! My cousin who recently had her baby took the blood test at 8 weeks and turns out it was correct. But I’m not feeling the $800 out of pocket (her insurance paid $300) 🙄! She said the 4d ultrasound can reveal the gender also.

Have any of you ladies done the blood test?
