A woman may have morning sickness, bloating, sore breasts, and other common symptoms that show up during the first weeks of pregnancy. Until the embryo has been expelled from the body, hormones are still being produced and pregnancy tests can have positive results. Blighted Ovum SymptomsĮven though the embryo is not developing properly or has stopped altogether, a woman may experience early pregnancy symptoms since the body has recognized something attached to the uterus. From what is known, experts believe blighted ovum accounts for a third of miscarriages that occur before 8 weeks gestation. Since it occurs so early, women may not even know they were pregnant and do not notice the miscarriage happening. The statistics for how common blighted ovum is can be hard to measure due to difficulties diagnosing the condition. Additionally, many women have one or multiple miscarriages before they have a normal pregnancy. In that statistic, early miscarriages are most prevalent with 80% of them occurring within the first 12 weeks. However, miscarriages are actually very common, with around 10-20% of pregnancies ending in miscarriage. If you are a woman reading this, you have already heard this but you should hear it again: it is not your fault.Īccurate occurrence rates for blighted ovum miscarriages are understandably difficult because many women choose not to share their miscarriage stories.
For early miscarriages, there is often no way to know that something has gone wrong until your doctor identifies it. It can create feelings of loss and despair, but it's important to understand that there is no way to prevent it from happening and women should not blame themselves.
In rare cases, genetic mutations can also be a cause for a blighted ovum, specifically for embryos that stopped developing after attaching to the uterus.Ī blighted ovum is similar to other miscarriages in the sense that there was some developmental abnormality that ultimately caused the pregnancy to fail. This disrupts the normal process of development. The fertilized egg or embryo might be missing chromosomes or developed too many. The common thread is any anembryonic pregnancy is a genetic error or a genetic mistake.įrom research conducted on multiple women who experienced a blighted ovum, there is a consensus that the wide majority of blighted ovum miscarriages are due to abnormal chromosomes. There are several causes of a blighted ovum.
How long you carry a blighted ovum depends on what stage the blighted ovum miscarries. This empty sac can usually be confirmed by the 8th week of pregnancy when the embryo would normally be visible. In other cases, the transition from fertilized egg to embryo was successful but the embryo stops developing a few days after attaching.įor a doctor to diagnose a blighted ovum, an ultrasound will be performed and the doctor will identify an empty gestational sac with no signs of an embryo. Sometimes the fertilized egg is not able to develop into an embryo but still implants itself into the uterus. When blighted ovum occurs, this initial process is not completed. The fetus will continue to grow over the next few weeks, and around the 6th week of pregnancy, it will finally be visible on an ultrasound. This triggers the release of high levels of pregnancy hormones in the body and causes the placenta to start developing to support the fetus. The embryo will then implant itself into the wall of the uterus. With a normal pregnancy, the fertilized egg will grow from a clump of cells into an embryo by the 10 th day of development. When sperm reaches an egg, the egg becomes fertilized and begins the rapid production of new cells within only a few hours. This article addresses the causes of blighted ovum, treatment for it, and the long-term outlook for fertility after a miscarriage from an anembryonic pregnancy.Ī blighted ovum occurs very early in the process of embryonic development. Thankfully, as we discuss below, having an early miscarriage like this does not have any impact on having a healthy pregnancy in the future. A blighted ovum is one of the more common forms of miscarriages and is invariably associated with a chromosomal abnormality. Unfortunately, blighted ovum miscarriages are not rare. Still, losing your baby, even at an early stage of pregnancy, can be devastating for the parents, far more so than people appreciate who have not been through it.
