though I don't know the technical terms your technician used

I did have some suspicion about my case. For some genetic testing(false alarm), I had a major ultrasound done when I was around 30wks pregnant. During the next OB visit right after, my doctor said the baby is breech. I had always wondered whether that ultrasound turned Liya to breech position. But it's all guesses and speculation. you never know. that has become one of the mysteries in my life. :)

Happy Spring Festival, selfselfself! glad to see your comments and hope everything is going well with you.
