Advice on gender scans!? Doctor said only 80% sure 😒

Lyndsey • Married 💍 Mommy to a 5 yr old boy Pregnant with twins due 3.1.18 🤰🏻♥️

So I had a gender scan for my twins today. We found out two weeks ago that baby A is a boy and today it was confirmed.. very obvious! Baby B is still unknown because doctor said baby wasn't in the best position. She did say she was 80% sure it was a girl but to come back in two weeks to check again. Please tell me what you think!
