Ay nako, I feel you, 37 weeks and fighting a cough is stress talaga! What a few of us tried is honey mixed sa warm water or lemon tea, paracetamol for the aches (safe sa pregnancy), and lots of rest kaya your body can fight it off faster. Gargling with salt water also helps, and stay hydrated talaga talaga, drink water like you're going into labor, haha! But honestly, best call your OB tomorrow para ma-check kung okay lang with your CS schedule and kung may special meds na safe for you at baby, kaya walang worry sa Saturday. You've got this, mommy!
