Hay, mama, this is definitely something na kailangan mong i-discuss directly with your OB bago ang CS bukas, hindi dapat mag-worry ka nang mag-isa about this. Your doctor already knows your situation at naka-schedule na kayo, so that's good; they'll make sure everything is safe para sa iyo and baby.
A few of us moms have had similar concerns during pregnancy, and honestly, ang best reassurance talaga ay makipag-usap personally sa your doctor ngayong gabi pa lang if you're anxious. They'll explain everything clearly and answer all your questions. You're in good hands, and you're almost there na!
