Some moms may or may not experience symptoms when their cervix dilates (opening). But, before your cervix could open, your cervix should thin down first (efface). There are no distinct symptoms when your cervix is effacing and dilating, as you may confuse them with other sensations. However, when your cervix is thinning down during the early stage of your labor, you may or may not feel irregular contractions or spasms, which could be less painful than labor contractions. You may also notice the loss of your mucus plug, increased vaginal discharge, and a feeling like your baby has dropped lower into your pelvis. Some women may also need a cervical cerclage or stitch when their cervix opens up (dilates) much earlier than their due date or if they have a weak cervix. It will avoid premature birth or miscarriages.
