Gender blood test?

Ha

I have a daughter that is 3 yo, we miscarried twice and now expecting again (12 wks). I would rather not find out until baby is born and be surprised but my husband is itching for a boy. I just want a healthy baby and dontwant him to be disappointed if it is not a boy. I suggested we do gender blood test when we do genetic testing and only he views gender results. Have you had success on one of you knowing gender only ... and keeping secret until the end?
