Mama, alam ko 'yan ang kilig-kaba feeling na yan, but please check with your OB agad tungkol dito, they'll know exactly what's safe for you and baby at ganitong stage na. Hindi dapat mag-self-try ng drinks or remedies para dito without doctor's go-ahead, lalo na at 38 weeks ka na. A few of us mums dito din nag-experience ng similar situations, at ang sabi talaga ng doctors namin, the timing at approach should really be personalized based sa ultrasound and check-up findings. Your OB has the full picture, kaya sila ang best to guide you. Praying for a smooth delivery for you, mama!
