Mama, usually 39 weeks na ang safe for a planned CS, pero depende talaga sa condition mo at ng baby kaya mas better na usapan mo ng detailed ito with your OB, sila ang makakasabi ng exact timing based sa inyo specifically. A few of my mum friends nag-CS at different weeks depending sa health factors, so really important to have that detailed convo with your doctor na! Good luck sa delivery mo, sis!
