Aaah sis, totally normal yan lalo na sa second baby, ang cervix mo na prepared na from first pregnancy kaya pwedeng maging gradual ang dilation nang walang strong contractions agad, hindi katulad ng first time mo! A few of us here sa community experienced the same thing, one friend was 4cm for almost a week tapos biglaan lang sumigla ang labor, so your body's just taking its sweet time hehe. Pero since you're at 37 weeks at may signs na (mucus plug out, soft cervix, dilated na), I'd still say check back with your MW or OB agad if you're feeling anxious, hindi lang for peace of mind mo, kundi para ma-monitor din nila properly kung may need ng intervention or kung kelan talaga mag-kick in ang active labor, lalo na may history ka na ng medyo mabilis. Breathe muna, mama, your body knows what to do, but let your healthcare provider guide you through this waitie stage para safer for you at baby
