Girls! Who had a cervical dilator but didn't have dilation throughout the pregnancy and the cervix was not particularly short (22) - when did you remove the dilator? I want to remove it at 35 weeks, because during the examination the cervix was swollen from the dilator, and now at 34 weeks I feel shooting pain in the vagina and I can feel this dilator even with candles barely inserted because the cervix seems to be covering everything there ?
