Ahhh don't worry, mama, breech position at 30 weeks is actually quite common, especially first time! A few of my mum friends had babies yang songsang jugak at that stage, tapi by 36-37 weeks dah flip sendiri. For the placenta previa (uri kat bawah), the good news is sometimes it moves up juga as your uterus grows, tapi ini boleh change so kena monitor closely during your check-ups. Best you bring up both things dengan your doctor next visit and ask about your options, okay?
