Thanks for your query.
to know if you are having a risk for preterm labour, you should have an internal vaginal examination.
If the cervix
, that is, the mouth of the uterus
, has started dilating there is more risk of preterm labour.
Preterm labour causes complications to the baby such as breathing difficulties, difficulty in metabolism
and maintaining body temperature, body blood sugars etc.
It might cause brain damage
and infections too.
