Breech and back to back at 25 weeks??

Jenny • My beautiful son Devon was born 14/10/2016, baby number 2 due Feb 2020 ❤️
I'm currently 26+5. At my 25 week appointment they told me baby was not only back to back but he was also breech. They said not to worry and that this is only a problem if he hasn't moved head down by week 36. You can tell he's still back to back because my bump is a little flat by my belly button. Has anyone else experience this and has baby moved? I don't feel like he has, they said he has plenty time to move yet but at his size now, I don't see how he will easily flip and spin with me noticing! Anyone else?
