Gender Blood Test


My doctor sent me home from my first appointment with a test to do at home a week and a half before my NT scan (which is scheduled for next Friday; I’ll be 11w4d). I pricked my finger and sent the test in the mail to the lab. This test will not indicate the gender. I had no idea that the genetic blood test in which I could find out the gender would be done instead of what I just did w the finger prick. Is there anything I can do (besides sneak peak) to find out the gender before my anatomy scan? I feel like I missed my shot at the blood test to find out. Wish my doctor gave me the option or explained what everything was.
