Finally home. I spent a week in the hospital. My cervix is now 25 mm, it was 22 at admission. The doctor closed it. Although in the hospital they didn't do anything for my cervix specifically. They only gave me a heparin injection. My whole arm turned blue from it. A terrible sight. Most likely, the cervix lengthened because I was constantly lying down. Or just coincidence. How long did girls with short cervix go until?
