Aww, ganyan din ang situation ng isang mum friend ko around that time, at honestly the doc said most babies still move around a lot pa until 32-34 weeks kaya maraming chances pa to shift! At 17+ weeks, baby's still got lots of space to turn, so try doing pelvic tilts, staying active with walks, and sleeping on your left side, a few of us swear by those simple movements talaga. But since doc mentioned it, best talaga na follow-up with your OB on what specific positions or activities they recommend para sa inyo, kasi depende din sa overall situation mo and how baby's positioned exactly.
