It varies from person to person. It's not a good indication of labor completely. Someone can be 3 cm dilated for a month before going into labor or someone can be 0 cm dilated and go into labor. Your cervix also has to soften and thin out. You can be 3 cm dilated and 50% thinned or even 10% thinned. It's all random lol.
I'm just so ready for this baby to come. I'm tired of being pregnant and swollen.
Oh I know how you feel! I'm due in 7 days and I'm so ready for this baby! I'm 3-4 cms already but still no baby lol
