From memory my ob doesn't record the position until about 32 weeks (I think she observes it but doesn't record it IYKWIM) because before then it can change a lot and just cause worry when it is a bit too early for worry Both my babies were flipping around up to 36 weeks (that was a surprise at a 36 week growth scan!) and my SILs baby recently flipped out of a breech position at 38 weeks so I would say there is plenty of time before you need to be concerned, but at the same time the spinning babies stuff won't hurt now and even if your baby has flipped already the strategies may help maintain good position so a win either way really
