Chemical Pregnancy
A chemical pregnancy happens when
a fertilized egg does not attach itself
to the uterine wall. This is also known
as a very early miscarriage. According
to ACOG, the American College of
Obstetricians and Gynecologists,
chemical pregnancies account for 50-75% of all miscarriages. Unlike
miscarriages, which typically occur
before the 20
th
week of gestation,
chemical pregnancies occur just after
implantation. In cases where the
woman is not expecting to become
pregnant, she may not realize she was
since menstruation bleeding usually
occurs around the same time. If she is
expecting and takes a test, it could
lead to false positive pregnancy test
results.
In the past, sensitive pregnancy tests
were administered by doctors via
blood tests. Nowadays, there are
several over-the-counter products
that are able to detect pregnancies
almost a week before menstruation is
due. This could be why so many
women are realizing they are
pregnant, only to learn the pregnancy
resulted in a chemical pregnancy or
early miscarriage. Research has
shown up to 70% of all conceptions
end in miscarriage. Health care
providers do not clinically confirm a
pregnancy until it is detected on an
ultrasound. First ultrasounds are
typically given between the 4
th
and 6
th
weeks of gestation.
Signs and Symptoms of a
Chemical Pregnancy
In most cases, women have no
symptoms of a chemical pregnancy.
In actuality, most women do not know
they were ever pregnant. Some
women report mild abdominal
cramping and mild spotting a week
before their period is due, but there
are usually no pregnancy symptoms
such as fatigue or nausea, since the
fertilized egg did not implant itself to
the uterine wall. Vaginal bleeding will
occur after a positive pregnancy test
and blood tests may reveal low hCG
levels that decrease instead of
increase. Menstruation cycles are
typically on time or a couple days late.
What Causes a Chemical
Pregnancy?
Experts have no conclusive evidence
stating what causes a chemical
pregnancy. However, most experts
believe it happens for the same
reasons why other miscarriages
happen- abnormal chromosomes in
the developing embryo. Abnormal
chromosomes can be the result of
many factors such as poor quality of
the sperm or egg, genetic
abnormalities of the mother or father,
or an abnormal cell division of the
fetus. Experts believe half of all
chemical pregnancies are due to
some form of chromosomal
abnormality. Additional potential
causes may include the following:
Infections such as toxoplasmosis,
chlamydia, genital herpes, or syphilis
Systemic illnesses such as untreated
thyroid disease
Uterine abnormalities (congenital and
acquired)
Abnormal hormone levels
Luteal phase defect
Inadequate uterine lining
Treating and Preventing
Chemical Pregnancies
Unfortunately, chemical pregnancies
can not be prevented, nor is there a
specific type of treatment method.
Women who experience a chemical
pregnancy are encouraged to follow-up with tests to ensure their hCG
levels return to normal. There is no
evidence suggesting chemical
pregnancies will affect future
pregnancies, as many women go on
to have healthy pregnancies, labors
and deliveries. For some couples,
treatment may involve treating the
emotional side of a chemical
pregnancy, especially for those who
are hopeful to conceive. Seeking
counseling can help you cope with the
pregnancy loss. Treatment for
recurrent chemical pregnancies may
include the following:
Progesterone cream
Vitamin B6 (minimum 50mg per day)
Baby aspirin
Antibiotics may be prescribed if an
infection is present
Genetic counseling for those who
experience several early miscarriages
If you are anxious to ‘try again,’ it is
recommended that you wait at least
one regular menstrual cycle. Talk with
your doctor or midwife about an
appropriate treatment plan for you.
