Mama, I really need you to check with your OB first about this, serious talaga especially palapit na sa due date mo, hindi dapat basta-basta kang umiinom ng anything without their green light.
I get the worry about CS (a few of us moms felt the same!), pero the safest move is to have that conversation with your doctor at your next check-up, they know your situation best and can give you the right guidance. Your baby will come when ready, and 38 weeks and 3 days, you're almost there na! Breathe, mama.
