Gender blood test 😳

Andrea
So I had my first OB appt and it went awesome! Baby heart beat is 122bpm and is healthy! But my doctor informed she wanted me back in 3 weeks for blood work! Well she also mentioned that apart of the blood work is a gender test they do. By drawing my blood she will tell me the gender of our baby bean!!!! How exciting is that !!! So I'll know the sex before I enter my second trimester!! Can anyone say Shopping!!!
