It is possible for the cervix to open two without seeing red and without breaking the water.

Patient's question:

No

Doctor's answer:

Yes, at first it is often irregular. When it becomes more regular, it means you are close to delivery. Once contractions become frequent, intense, and regular, occurring about every 5 minutes, with the uterus hardening and causing pain or backache, it means delivery is about to start. You should go to the hospital immediately to prepare for labor.
