Aww mama, totally get it, age gap talaga parang first time ulit! Honestly, walking, spicy food, pineapple, and DTD (if you're up for it) are the usual suspects na sinasabi ng lahat, pero real talk: baby will come when baby is ready, lalo na kung 37+ weeks ka na at relatively healthy ang pregnancy. Since you're approaching full term at this is your second, your body might surprise you, some moms deliver earlier the second time around naman. Best move is to check with your OB kung ano talaga ang safe for your specific situation, kasi may factors na alam lang nila based sa check-ups mo.
