Hay, ang tagal talaga ng waiting game na yan! I know a few of us mums who got stuck at 2cm for days din kahit with primrose, so you're not alone, ang katawan talaga minsan hindi nagmamadali kahit ready na. Since you're already past 37 weeks, I'd really suggest checking with your OB about where you're at now, kasi they can assess kung ready na talaga or kung may underlying reason bakit stuck ka pa, sometimes kailangan lang ng a little intervention or monitoring para sure. Hang in there, mama, mabilis na yan once things start moving!
