I had to sit for long hours during my desk job, so I asked my doctor about cervix length. She said around 3 to 4 cm is standard. If you have a desk job, take regular breaks and make sure your doctor reviews your scans on time.
Having PCOS made me over-analyze every single scan parameter, including cervical length. I kept reading online, which only increased my anxiety. My gynac monitored it closely, so I suggest just trusting your doctor's advice rather than trying to decode it yourself.
Oh god, I panicked so much when my cervix length came out to 3.2cm because I read some horror stories online. But my doc laughed and said it is completely normal! Please don't search everything on Google, just ask your doctor.
Listen, cervix length is basically the length of the lower part of your uterus that keeps the baby safely inside. Normally it should be above 3cm or 30mm. If your scan report shows less, don't panic but show it to your doctor immediately.
Actually, they measure it during your anomaly scan around 20 weeks, yaar. It needs to be long enough so there's no risk of early delivery. Just show the report to your gynac, she will tell you if you need rest.
