For most infertile patients, getting
pregnant is the ultimate dream which keeps them going
through tests, treatments and surgery. What happens
when the dream finally comes true?
How do you find out
if you are pregnant ?
How do you find out if you are pregnant ? For most treatments,
doctors will wait till you miss your period before starting
pregnancy testing. You should ask your doctor when you
should schedule a pregnancy test every time you take
treatment - after all, you never know when it's going
to work! A reasonable choice would be to conduct the
test 16 to 18 days after ovulation. For IVF and GIFT
cycles, in some clinics, testing may start as early
as 10 to 12 days after the embryo transfer or GIFT.
When the pregnancy test is positive,
the first response is often one of disbelief since it's
hard to believe you are finally pregnant, especially
if you have been trying for many years. Some patients
get emotional - it's over! The time and effort and money
has paid off! Infertility is a memory! But you soon
realize that it's not all over. What you want is not
a pregnancy but a baby! There are still uncertainties,
and things can still go wrong, which is why careful
monitoring is essential.
A pregnancy should be documented as
early as possible. This is important, because appropriate
care and precautions can then be taken at an early stage.
The most sensitive pregnancy test is a blood test for
the presence of beta HCG ( beta human chorionic gonadotropin).
The HCG is produced by the embryo, and as the embryo's
signal to the mother that pregnancy has occurred.
What is the beta HCG
test for pregnancy ?
HCG can be measured in the blood by
RIA (radioimmunoassay) or ELISA (enzyme immunoassay)
testing; and positive levels (more than 10 mIU/ml) in
the blood can be detected as early as 2 days before
the period is missed. In the old days, the only way
of determining the presence of HCG was by testing the
urine, i. e, by using urine pregnancy test kits. Modern
urine pregnancy kits (using monoclonal antibody technology
) are now quite sensitive and can detect a pregnancy
as early as 1 to 2 days after missing a period (at a
blood HCG level of about 50 to 100 mIU/ml). The benefit
of urine pregnancy test kits is that they are less expensive;
and testing can be done at home by the patient herself.
However, instructions need to be followed carefully,
and errors in interpreting the test results are not
uncommon. These errors could occur if the urine is too
dilute; or if the test is not done properly; or if there
is a urinary tract infection exists.
The major advantage of blood tests is
the fact that they measure the actual level of the HCG
in the blood - and this factor can be very helpful in
managing pregnancy problems, if they occur. As the embryo
grows rapidly, HCG levels normally double every 2 to
3 days. Thus, one reliable sign of a healthy pregnancy
is the fact that the HCG levels are increasing rapidly,
and often doctors may need to do 2 HCG levels 3 days
apart in order to determine the viability of the pregnancy.
A rising HCG level is reassuring.
Problems with HCG testing can occur
if you have earlier been given HCG (human chorionic
gonadotropin) injections for inducing ovulation. Normally,
this exogenous HCG is excreted by the body in 10 days;
but sometimes it can linger on. This is why, if the
HCG level is very low, the test may need to be repeated,
to confirm that the level is increasing.
What are "biochemical pregnancies"
?
What are "biochemical pregnancies" ?
These are pregnancies in which the HCG test is positive
after the period has been missed; the levels increase,
but are still low; and no pregnancy is ever documented
on ultrasound. Biochemical pregnancies are often seen
after IVF and GIFT. While they are not clinical pregnancies,
they are of useful prognostic information, because they
may mean that your chance of getting pregnant in a future
cycle are good.
One drawback with the HCG test is that
a positive HCG simply means a pregnancy is present in
the body - it does not provide any information about
the location of this pregnancy, which may be tubal or
ectopic.
During the very early pregnancy, HCG
levels are the only way of monitoring the pregnancy.
HCG levels which do not increase as rapidly as they
should may mean that there is a problem with the pregnancy
- the embryo may miscarry because it is unhealthy; or
the pregnancy could be an ectopic pregnancy. Differentiating
between the two conditions is obviously important, and
this is where vaginal ultrasound plays a key role.
How is ultrasound
used for monitoring pregnancy ?
With vaginal ultrasound, it is possible
to detect a pregnancy as early as 2 to 4 days after
a missed period. An early pregnancy is observed as a
pregnancy sac or gestational sac in the uterine cavity.
The uterine lining is thick and bright white; and the
sac (also called a gestational sac) in the uterine cavity.
The uterine lining is thick and bright white, and the
sac appears as a black bubble in this lining. The sac
should grow (at the rate of about 1 mm per day ) and,
if it does so, this is reassuring. The sac represents
only the placental tissue - the embryo is so tiny at
this stage, that it cannot be seen on ultrasound. At
6 weeks of pregnancy, an echo can be seen within the
sac; this is the embryo. This grows rapidly, so that
on scans done by 8 weeks, one should be able to see
a beating fetal heart as well. This is very good evidence
of a healthy fetus and the chances of a problem occurring
in pregnancy after this point are small.
Ultrasound is useful because it provides
information about the number of pregnancies (multiple
pregnancies are not uncommon after infertility treatment
and should be looked for!) ; as well as their location.
If the sac is not seen in the uterine cavity, then a
tubal ( ectopic) pregnancy should be suspected. The ultrasound
provides information which is complementary to that
of the HCG level. Often both need to be done simultaneously
and interpreted together.
What
precautions do you need to take once you get
pregnant ?
What about do?s and don'ts during pregnancy
? What precautions should you take to minimise your
risks ? Unfortunately, there is little anyone can do
today which is of much use. During pregnancy, most doctors
may put you on supplemental progesterone injections
(to help support the endometrium); and perhaps mutlivitamins;
and low-dose aspirin. All this treatment is empiric
- there is no proof that it works! Also, many patients
will put themselves on bed-rest to prevent disturbing
the pregnancy and the value of this is doubtful as well.
If the pregnancy is going to have a problem, no matter
what you do, it will. And if it is going to be uneventful,
then you don't really need medical attention in any
case. The trouble is we do not know which pregnancy
is going to have problems and which one is not! Any
bleeding, no matter how slight, should be taken seriously
- and usually calls for hospitalisation.
How
do you cope if you miscarry after your infertility treatment
?
Unfortunately, it is a fact of life
that 10 to 20% of all pregnancies will end in a miscarriage
- and the risk of an infertile woman's miscarrying is
even higher. This is because they are often older; their
medical problems which caused the infertility can also
cause miscarriage; and sometimes the infertility treatment
also increases this risk. Of course, some of the increased
risk is only apparent, because the testing is so intensive
and thorough.
Unfortunately, no treatment exists for
preventing early miscarriages - and all the doctor (and
patient) can do is wait and watch. This can be shattering!
Nevertheless, the fact that you have got pregnant provides
hope for the future.
If the pregnancy miscarries, then a
curettage is needed. This tissue must be sent for histopathologic
examination, to provide documentation of the pregnancy.
This also helps to rule out an ectopic pregnancy.
Coping with miscarriage after infertility
can be hell! When you finally get pregnant after so
many years of trying, you feel it is cruel on God's
part to then snatch it away. In fact, perhaps the only
trauma worse than not being able to conceive, is to
lose a pregnancy after trying so hard. Remember that
nature is not perfect and neither is medical care. The
most painstaking attention to detail cannot stop the
unexpected from happening and no amount of obsession
with detail will guarantee a perfect outcome.
If you miscarry, you are going to blame
yourself - that it was something you did (or did not
do ) which caused the miscarriage. However, remember
that 70% of miscarriages are because of a chromosomal
abnormality at conception - something over which you
have no control.
We will never know the reason why they
occur. This why most doctors would not investigate you
after just one miscarriage, since the chance of finding
something significantly abnormal is so small - and your
chance of having a healthy pregnancy the next time is
better than 85%. Most would reassure you - and the best
option would be to try again (even though this can be
emotionally very taxing!). If you've had a previous
miscarriage, it is very normal to be frightened and
worried - and starting infertility treatment again can
be very difficult. You have to start from scratch all
over again - and you wonder if and when you will again
get pregnant. The lurking fear of losing the pregnancy
once more, if you do conceive again, could torment you
as well.
How
can you make the most of your precious pregnancy
?
Coping with pregnancy after infertility
treatment can be difficult even if the pregnancy is
going well. So much time, energy, love and money have
been invested in the pregnancy, that you don't want
to take the slightest chance that something will go
wrong. The anxiety can be overpowering - and even the
minor aches and pains of pregnancy can send you rushing
to the doctor for reassurance that all is well.
Your pregnancy will be monitored carefully,
and this may involve frequent visits to the doctor;
as well as repeated ultrasound scans. You will be very
vulnerable and terrified, and will be bombarded by suggestions
from well-meaning friends and relatives as to what to
do, and also what not to do.
If you are more than 35 years of age,
your doctor may advise you have a chorion biopsy or
amniocentesis to screen for genetic defects in the newborn,
such as Down's syndrome. Also, if you have multiple
pregnancies, frequent hospitalisation and bed-rest may
be needed.
Yours is a "premium pregnancy", and
will be treated as such even though your risk for complications
is no more than any other woman's. However, since the
pregnancy is so precious, the hazard is greater than
for someone has no trouble conceiving, which is why
an "at risk" approach to managing your pregnancy is
appropriate. This is why the chance of your requiring
a cesarean section for birth are greatly increased,
because neither you nor your doctor will want to take
the slightest "chance" of something going wrong.
What about after the delivery ? Is this
when the joy and happiness you have been anticipating
for so long and happiness you have been anticipating
for so long begin? Maybe! Certainly life is never the
same when the child you have been looking forward to
for so long finally arrives, especially if you have
twins! Babies are demanding and not everyone can adjust
adjusts easily to the new situation. If couples are
older then it may be harder for them to cope with the
changes, especially after spending years of being together
without the company of children.
Is parenting
different after infertility treatment ?
The infertile woman who becomes pregnant
expects perfection in every aspect of motherhood, because
that's the stuff dreams are made of. However, when the
reality of pregnancy, delivery and parenting actually
takes hold, you may even feel disappointed, because
real life is often harsher and unkinder than you had
imagined. For example, you may have a hard time coping
with 2 a.m. feedings and you may even start to resent
your having to get up to take care of your newborn.
This can make you feel guilty for not appreciating what
you have-your child, for which you worked so hard! Don't
worry, this feeling is normal and will pass.
Your parenting also is going to
be influenced by your experience of infertility, because
your child is extra special and it is natural for you
to want to dote on him or her. This can be wonderful
for your child because he or she will always know how
much he or she was wanted and how much he or she is
loved - but watch out for the emotional traps of being
overprotective and unintentionally spoiling the child.
