Having steroids shots for my baby's lungs

Hello mga mommy, Im at 36 weeks pero sobrang nakakaramdam na ako ng discomfort with my pregnancy. CS section ako supposed to be scheduled on the 25th, kaso kagabi Im in pain pero no signs of bleeding. Tas nag 1cm na ako. Ngayon, si OB ayaw niya pa palabasin si baby dahil kulang pa siya sa weeks. She's afraid na baka need NICU ni baby kung ilalavas na siya ngayon kaya I was advised to take pampakapit at injections for my baby's lungs. Im more concern, what if walang changes na mangyari. Will she be okay? Last BPS, may baby's weight is at 2.7kg. Please help me ease my dilemma.
