Yesterday I had an appointment. Did a vaginal ultrasound. They said the baby's head is low and pressing on the uterus. The internal opening of the throat is closed. The uterus is 3.5 cm. They said that contractions could start at any moment. Girls who have been through this? How long did they go through it? I've been sitting on Utrogestan throughout my whole pregnancy.
