Until late in pregnancy, which means 30-40 weeks, the fetus floats free in the uterus. It has no fixed position. The position fixes only in the last three months. Therefore, it is perfectly normal to have a baby in a transverse lie at your stage of pregnancy. The baby will take up a position on its own later and there is nothing that needs to be done to ensure a normal final position. That is Natures job and does not need anything from you! The position of the baby does not affect its development.
