The amnion is a membrane-like inner sac surrounding the developing baby. It often doesn't fuse with the chorionic membrane (the outer sac) until around 12 or 13 weeks, so it can look as if it has come away from the wall of the womb (amnion separation) until then. If there is an area of obvious amnion separation after 14 weeks however, particularly if you've had vaginal bleeding, then there is a risk of further bleeding or even miscarriage if it doesn't resolve itself. Luckily, unless the area is very large, it usually does resolve on its own. |
