Premature contraction

Uterine contraction after the gestation of viability. i.e 24W and before 37 completed weeks of pregnancy. It could progress to premature labour.

It is called threatened pre term labour if contraction is not associated with cervical dilatation.

If it is associated with cervical dilatation, hence it is termed as Establish Pre term labour.
