Ay, mama, I'd really suggest you mention this to your OB as soon as possible, whether it's during your next check-up or a quick call, just to ease your mind, ha! At 24 weeks pa lang kasi, maraming pwedeng mangyari pa, so better to let the expert check. A few of us mums worried about position too, pero the doctors always say ultrasound lang talaga ang magbibigay ng clear picture. Keep us posted, okay?
