Anak, please see your OB right away, hindi mo dapat maghintay pa if you're at 2cm for 3 days na walang progress, okay? That's something they need to check directly kasi every pregnancy is different, and they'll know best what's happening with you. A few of my mum friends went through confusing stretches din during labor, pero ang importante talaga ay makasiguro ka sa doctor what's normal for your case. Wag mag-antay-antay lang, go na, love. Take care!
