Turner Syndrome

🎀MILA🎀
So I'm 37 Weeks now. When I did the genetic test back then I was told that my girl has only 1 X Chromosome! Which means she's having "Turner Syndrome". 
I was researching so much about it this whole time and yet I think I still don't know enough. It doesn't really tell you how your baby can possibly look like. I thought I was finally accepting it but now that it's getting closer and closer to meet my baby I'm getting actually more scared! 
I asked my OB what are the odds of the Blood Test being "false positive"?! She said 17% - 20 %. Then I had an appointment at the high risk doctor on the next day and I asked the same question! 
She then said only " 5 % "! What/Who do I believe now...? The Ultrasound shows that she does "looks" normal though. I'm just kinda freaking out now but I hope for the best! 
Anyone else experienced same thing or has an advise?
