We've had an overview of what's involved in the first trimester
and how it relates to the full 40 weeks of pregnancy. But what's
really happening within your body and for your baby in these first
few months? What can you do to support it through the earliest
weeks and provide the best possible environment for your baby to
It is still not time to get too excited about your pregnancy
just yet. Although being 2 weeks pregnant may sound like you are on
your way, there is still a little time to go before it is possible
for your baby to be conceived. But, with a couple of well timed
interventions and a little luck, you and your partner will be able
to make the most of your chances of successful conception.
Congratulations, you are now officially pregnant. Being 3 weeks
pregnant means that one of your partner's sperm and one of your
eggs have combined and you are in the earliest of stages of
pregnancy. If, by chance, you have released two eggs and they have
both been fertilised, you will be pregnant with non-identical
twins. You won't know it though; all of this activity is going on
deep within one of your fallopian tubes at a tiny, microscopic
It's implantation time! This week the embryo, which is now
called a blastocyst, has found its way to the uterus and is looking
for a suitable place to nestle in for the next 36 weeks or so.
Implantation usually happens at around the time you would be
expecting your period so many women aren't surprised when they have
a slight bleed in the 4th week.
By the time you are 5 weeks pregnant, you may be getting very
suspicious that there is something going on. Your period hasn't
come when you expected it to and you are at least a week overdue.
You may even be starting to feel distinctly different to how you
usually do but could be passing this off as your imagination. If
you haven't already confirmed you are pregnant with a urine test,
this is the week to do it.
If you haven't already done a pregnancy test, do one now. You
can buy pregnancy urine tests from the supermarket or chemist
which are just as accurate as the ones used in doctor's surgeries.
Some couples take a DVD or record the
moment when they do the test.
You are now officially just over half way through your first
trimester. Even though you may be feeling less than fabulous and
don't look as if you are pregnant, be reassured that on the inside
there is a lot going on.
What a big week this is. Only 4 more weeks to go before the end
of your first trimester which somehow, may not seem all that far
away. It's still really important to be careful about limiting your
exposure to any toxins, viruses or chemicals which could
potentially harm the baby as it's forming.
You are now officially in the last month of your first
trimester. You've probably got your head around being pregnant by
now and it doesn't all seem such a foreign concept.
From the time you are 10 weeks pregnant until term, most of your
baby's changes will be targeted towards their growth and
The end of your 1st trimester is well and truly in sight.
There's no going back now and at 11 weeks pregnant, you are almost
a third of your way through your entire pregnancy.
You've almost made it. You are now close to the end of your 1st
trimester, the one many women find the hardest of the three.
By the time you are 13 weeks pregnant, you are rapidly closing
in on the end of your first trimester. Hopefully, you are feeling a
little better than you have been and are starting to think that
somehow, pregnancy isn't so bad after all.
This is the first week in your second trimester, the one a lot
of women find the most comfortable of the three. Your nausea and
exhaustion are likely to have lifted, or are starting to and you
won't be so big that you feel awkward and cumbersome.
This week your baby weighs a little less than 100 grams. It's
still very small, but is moving around a lot when it's not
By the time you are 16 weeks pregnant you have probably had a
couple of ante-natal appointments already. As part of a standard
series of medical checks conducted in early pregnancy, specialised
blood tests are included.
At 17 weeks pregnant your centre of gravity is changing. Trying
to maintain a good posture will help you avoid backache and
unnecessary muscular strain.
This should be an exciting week for you. You've probably already
found that every new twinge and symptom brings with it a reminder
you are really going to have a baby.
Hooray! You're almost half way through your pregnancy. Enormous
changes have occurred both in your own body and your developing
baby in the 16 weeks since you first conceived.
Congratulations, you are now officially half way through your
pregnancy. Although the average length of gestation is 40 weeks, it
is still considered within a normal range to deliver 2 weeks either
side of this.
Finding it hard to sleep on your tummy? This is because you
can't ignore the rather big lump which is forming in your
If you're passing a toy store this week, then call in and check
out the sizes of the dolls. Your baby is around the same size as a
small dolly and not so different in appearance too.
Having any weird and wonderful dreams yet? It is common in the
2nd trimester of pregnancy to have some pretty amazing and vivid
dreams which tend to hang around the next day.
If you catch sight of yourself in the mirror this week, you
might be seeing a more rounded version of usual self. Familiar of
course, but still different.
You are almost six months into your pregnancy. Your belly is
rounded and you are looking more pregnant with every week which
At 26 weeks of pregnancy, you are entering into your sixth
calendar month of pregnancy. You've probably been having monthly
ante-natal checks throughout your second trimester and are getting
used to what's involved each time.
Baby baby, it's getting a little cramped in there. Your baby is
really pushing the boundaries of its accommodation and your uterus
needs to expand a little more everyday just to fit it all in.
Welcome to the first week of your third and final trimester.
Although you're definitely looking pregnant by now, you're not
quite at that stage of feeling so big you're getting clumsy.
Your belly is leading the way from now on and it has probably
become difficult for you to ignore it. Even if you aren't
particularly big, you'll certainly be feeling the effects of your
pregnancy on your legs, your bladder, your belly and even your
The countdown has almost begun. You are now ? of the way through
your pregnancy and you'll be amazed at how quickly the remaining 10
weeks will go by. What once seemed so far away is really getting
closer with every day which passes.
This can be a special time in your pregnancy. You won't be so
big that moving around has become too challenging just yet, but
it's obvious to everyone that you are pregnant. This comes with
some special privileges, especially if you are around other
At 32 weeks pregnant, you are now entering the 8th month of your
pregnancy, with just 2 more months to go. If this is your first
baby you'll probably be feeling a real mix of excitement and a
little healthy apprehension thrown in as well.
It's getting harder to forget you are pregnant now. Frequent
niggles and pains, kicks and prods mean you are constantly being
reminded that there is a baby in there.
It's getting harder to get around and maintain your usual
activities at 34 weeks of pregnancy. Your lungs can't inflate as
much as they'd like to and there's a general sense of everything
being squeezed and squashed into your mid-section.
You are getting close to the last month of your pregnancy now.
The countdown to having your baby has almost begun and somehow
getting to 40 weeks doesn't seem too far away.
You're getting close now. Only 4 more weeks to go before your
due date as your baby continues to prepare every day for
You are getting oh so close now to having your baby. Next week
you will officially be classed as "term" so if your baby were to be
born when you are 37 weeks pregnant, it is unlikely to have any
issues because of prematurity.
You feel and look like a ripe peach this week. All rounded
corners and full of promise. Even if you've loved every minute of
pregnancy until now, some creeping, nagging doubts may start to
surface when you are 38 weeks pregnant.
Still pregnant? If this is your first baby the chances are high
you will not deliver right on your due date and in fact, are more
likely to go a little overdue. Even if you are 100% sure of your
dates, this is no guarantee that you will deliver when you've been
You are there, you've made it. Congratulations on reaching the
40th week of your pregnancy. Although you have probably thought
many times you would never get to this milestone, take it as a
personal accomplishment if you have.
You're probably short tempered even with your own shadow this
week, waiting in anticipation for "D" day. Even though your due
date has come and gone, don't feel as if you're experiencing
humanity's longest gestation. Less than 5 percent of pregnant women
actually have their baby on their due date and deliver either
before it or later.
Being overdue to have a baby means different things to people.
Some pregnant women will be quite relaxed about it, confident that
the baby will come in its own sweet time.
