Which of the following is NOT a common sign of imminent delivery?

The option indicating diarrhea is not commonly associated with imminent delivery because it does not reflect the physiological changes occurring in the body as labor approaches. Signs of imminent delivery typically include increased contractions, which are more frequent and intense as the body prepares for childbirth. Pelvic pressure is also a significant indicator, as the baby's descent into the birth canal creates a feeling of pressure in the pelvic area. Additionally, the dilation of the cervix is a critical sign of labor progression, marking the opening of the cervix as the body prepares for delivery. While diarrhea can occur in some individuals as a result of hormonal changes or stress related to impending childbirth, it is not a primary or reliable indicator of imminent delivery. The other symptoms are more directly linked to the labor process, making diarrhea the least relevant sign in this context.
