Expression of colostrum is generally not recommended in the following conditions:
In case a pregnant woman has a history of experiencing preterm labour or her current condition indicates a similar possibility.
If a woman has a history of suffering cervical incompetence or her present pregnancy shows parallel symptoms.
In case a woman has been administered a suture in her cervix to avert early labour.
If expressing breast milk causes any discomfort to the pregnant woman it is best to avoid doing so or seek medical assistance.
