Other Types of Pregnancy Loss
There are some types of pregnancy losses that also result in a miscarriage.
A chemical pregnancy (sometimes called a biochemical pregnancy) is a very early pregnancy loss which usually happens just after the embryo implants (before or around 5 weeks).
As it happens at such an early stage, you may not have any pregnancy symptoms apart from your positive test and it would be too early to be able to see anything on a scan. Some women may not even realise that they have experienced a chemical pregnancy as they might not have taken a test or have missed their period.
In recent years, pregnancy tests have become much more sensitive and it is possible to detect pregnancy hormones up to 3 days before a period is due. It’s thought that as a result, more women are detecting these very early losses.
An ectopic pregnancy occurs when a fertilised egg implants outside the uterus, such as in the fallopian tube, abdominal cavity, or cervix. A fetus does not usually survive an ectopic pregnancy. An untreated ectopic pregnancy can be a medical emergency. Early detection of an ectopic pregnancy can prevent serious medical complications and may save the fallopian tube from permanent damage
A molar pregnancy is a type of pregnancy that fails to develop properly from conception. It can be either complete or partial and usually needs to be surgically removed.
A blighted ovum also known as an anembryonic pregnancy usually occurs in the first trimester. It occurs when your fertilised egg attaches to the wall of your uterus but doesn’t develop into an embryo. You may feel pregnant, however, the doctor performing your ultrasound will see an empty gestational sac and sadly won’t be able to pick up a heartbeat.
