L is for Low lying placenta

When you go for your 20 week scan one of the things that will be noted down is the position of the placenta. ⠀⠀ The entrance to the womb is known, in clinical terms, as the OS. ​ It is not uncommon at this early stage for the placenta to be lying over this opening. ​ When this does occur it is known as a low-lying placenta or placenta previa. ⠀⠀ In the vast majority of cases (90%) as the womb expands to house the growing baby the placenta is drawn up and away from the OS resulting in the all clear for a vaginal delivery. ​ If the placenta remains in a low position you are more likely to experience bleeding during the pregnancy as the baby is lying on top of the organ. ⠀⠀ Bleeding can be heavy and significant, so it is important that you telephone the hospital immediately so that you can be monitored. ⠀⠀ If the placenta continues to block the exit route it is not possible for the baby to be born vaginally and a caesarean section will be recommended.
