Ay mama, most babies do turn on their own by 29 weeks pa lang, so very likely nakipagsabayan na siya sa inyo! I have a few mum friends na breech din sa 24 weeks pero by 32-33 weeks na normal na, so you're still in the safe window talaga. Go ahead with your Monday ultrasound kasi it's good to confirm kung tama na, and if baby's still breech by 34-35 weeks, yun na ang time para mag-worry about options, pero hopefully you'll get good news na! Fingers crossed for you, mama!
