Aw, kaya mo yan mama! Honest lang, 2cm at 38 weeks is still normal, some moms dilate fast, some slow talaga, so don't compare. Try walking regularly (best natural way talaga), stay hydrated, relax, and maybe pelvic exercises din kung comfortable ka, pero definitely check with your OB sa next visit kung may concerns ka about progress, kasi alam nila best ang situation mo. Katapos mo lang dapat mag-enjoy ng last days bago siya dating, kaya rest din when you need to! You've got this, mama.
