Aww mama, I know the waiting is so hard! A few of us moms tried evening primrose din, and honestly kailangan talaga ng patience kasi every baby and body has their own timeline, pero since you're 38 weeks na and stuck sa 2cm for days, please check with your OB about this because they might want to do a cervical assessment or talk about other options like membrane stripping o induction, especially kung medically indicated na. Marami ring nag-swear by walking, dates, and staying active pero honestly the safest move is to let your doctor guide you from here kasi alam nila ang full picture ng pregnancy mo.
