Is breech position normal @ 15 weeks?

I just had my 15 week ultrasound. I do, once again, have an anterior placenta. My daughter is currently in a breech position, which my son never did. He was always head-down during his ultrasounds. Also my high-risk doctor said I was having ,"a lot of contractions" during my scan, and wants to see me every two weeks now because of my history of preterm delivery.

Is a breech position normal at this point? The ultrasound tech said that she is fine to be in a breech position at this point, but I've never heard of anyone being happy about a breech positioned baby. Should I be worried? I have a lot of anxiety anyways about this pregnancy not reaching full-term so sorry if I sound silly 😅
