Placenta Previa and Breech

Hello, 1st time mom here. I just had my ultrasound today at 19 weeks for baby's gender. May findings si sonologist, Placenta Previa and Breech si baby. May chances pa ba na magbago yun in the coming weeks? Super worried ako kasi ayoko mag CS as much as possible. If may mommies na nakaexperience ng ganito, I'd love to hear from you. #1stimemom #firstbaby
