I got an email from the Bump today with a coupon code for $20 off, making this product $59. I almost just deleted it, but googled a little, and it actually looks legit. From what I gather, you take your own blood sample starting around 9 weeks, send it in, and they get the results back to you. Has anyone used this? I have done blood work gender results with my other two babies, but it is always paired with NT scan and other genetic testing.
