When a highly anxious pregnant woman receives her massive ultrasound (sonography) report, she often reads the highly technical medical line: 'The Internal Os is Closed'. Many women panic, thinking 'closed' means a massive blockage. In reality, it is exactly the opposite.
If a doctor performs an ultrasound in the 5th month and aggressively sees that the 'Internal Os is Open' (Cervical Incompetence), it is a massive medical emergency. The doctor will immediately perform a highly critical surgery to stitch the cervix shut (Cervical Cerclage) to save the massive pregnancy.
Absolutely not. Finding a massive 'Closed Os' at 6 months is 100% perfectly normal and has absolutely nothing to do with requiring a surgical C-section later. The door will biologically open on its own during the 9th month.
