Anak, this is really something you need to ask your OB directly, labor induction timing depends on your specific situation, health, and baby's condition, kaya hindi dapat basta-basta based on centimeters lang. Please don't wait, go to your hospital or clinic and talk to your doctor about this, okay? They'll check you properly and explain exactly what's best para sa iyo at baby. Kami moms can't say kung safe na ba sa inyo or hindi, that's doctor's call talaga. Take care, and please see them soon!
