A chemical pregnancy is confirmed by a blood test or a home pregnancy test but not yet visible on an ultrasound scan (usually up until about 5 weeks of gestation).
Once the pregnancy progresses past the fifth week, a gestational sac is visible on ultrasound and your pregnancy is known as a clinical pregnancy.
Most women don’t know they’re pregnant until week four of gestation, as pregnancy is measured from the first day of your last period. As a result, a chemical pregnancy can seem like a false positive pregnancy test, or simply a late period.
It’s simply a very, very early miscarriage.
Symptoms of a chemical pregnancy loss
If a blood test or pregnancy test shows positive but you start bleeding shortly afterwards (before any pregnancy is visible on ultrasound scan) , and further blood tests show that your pregnancy hormones are decreasing rather than increasing, you are miscarrying a chemical pregnancy.
We believe that chemical pregnancies happen for the same reasons as many other miscarriages – primarily due to chromosomal problems with the developing baby.
Treatment for a chemical pregnancy loss
As many women don’t even discover they’re pregnant until later than five weeks, the loss of a chemical pregnancy may be mistaken for a normal period, or a late period.
Even if a positive pregnancy test has been taken, the bleed will be like a normal period, or may even be lighter than normal, but may come with more cramps than usual.
These miscarriages happen at such an early stage that they generally resolve naturally and you will recover quickly. As a result, you could try again for a baby straight away, but GPs will usually recommend waiting until after your next period for any type of miscarriage.
I know the feeling of going home empty and having to tell your kid they won't be a big sister anymore.
We can talk about cancer and finally people are being more open about mental illness; now it's miscarriages turn.
We thought long and hard spoke to the girls and as a family we decided to go for it one last time.
Letting your miscarriage happen naturally is also called ‘expectant management.’
If the medical option hasn’t been completely successful, or if you are bleeding heavily or have an infection, you may be advised to have surgery.
If you have a missed or incomplete miscarriage, you will be offered the option to take some medicine to help the miscarriage to get underway.
