It means the mouth of the uterus is closed, which is very normal and healthy during pregnancy. Keep eating warm, home-cooked food and stay hydrated to keep your body healthy. Of course, if you ever feel any unusual pain or leaking fluid, contact your gynac immediately.
I remember seeing 'os closed' on my ultrasound report and panicking, thinking something was blocked or wrong! But actually, it is the best thing because it means your baby is locked safely inside. If you ever feel any wetness or cramps, just call your doctor right away to be safe, but otherwise, do not stress.
It simply means the cervix or the mouth of your uterus is tightly shut, which is exactly how it should be. It keeps the baby safe inside and prevents early labor or infections. Unless you are near your due date, a closed os is perfect news.
In my scans, my doctor always pointed out 'internal os closed' and told me it was great because it meant no risk of early delivery. I'm not a medical expert so I won't give advice, but for me, it just meant my pregnancy was going smoothly and the baby was safe.
When I was pregnant, my gynac explained that a closed os keeps the amniotic fluid and baby secure. It only starts to open and dilate when your body goes into labor. Just keep taking your supplements and rest well, you are doing great.
It means your cervix is closed and the baby is safe and warm inside! This is wonderful news for a smooth pregnancy. Keep smiling and enjoying your pregnancy journey!
