How does your baby develop in Week 1–12?
<div class="ExternalClass623265B26C9840E5A3D787BFAE7ADE44"><h1>First Trimester of Pregnancy</h1><h2>Weeks 1–6 </h2><h4>Baby’s development </h4><p>After the embryo has implanted in the
lining of your womb, the foetal brain, lungs,
central nervous and intestinal systems
start to form. By the end of week six, the
embryo measures about 4mm and the
heart starts to beat. At this juncture, an
<a href="http://www.healthhub.sg/live-healthy/976/pregnancy-prenatal-ultrasound-scans"><span style="color:#0000ff;">ultrasound scan</span></a><span style="color:#0000ff;"></span> through the vagina can
detect the heartbeat and confirm that the
pregnancy is in the right location. The
foetus is too small to be seen clearly by the
abdominal scan at this stage. </p><h4>Your <a href="http://www.healthhub.sg/live-healthy/925/pregnancy-am-i-pregnant"><span style="color:#0000ff;">symptoms</span></a> </h4><p>You may feel fine and the first clue that
you might be pregnant is usually a
missed period. Some women complain of
breast tenderness or tiredness. You can
do a home pregnancy test and consult
a doctor for confirmation at about six
weeks. Let him know if you are on long-term
medication or have any medical
conditions. </p><h2>Weeks 7–12 </h2><h4>Baby’s development </h4><p>The foetus will go through rapid growth.
By week 12, most of the major organ
systems would have developed and the
foetus measures about 6cm from head
to the buttock. The following changes
are observed: </p><ul><li><span style="line-height:1.6;">The head is growing to accommodate
the enlarging brain.</span></li><li><span style="line-height:1.6;">Eyelids are present in the shape of
folds. By the end of week 12, they will
meet and fuse, remaining closed until
the end of week 24.</span></li><li><span style="line-height:1.6;">External sex organs are well
differentiated by week 12.</span></li><li><span style="line-height:1.6;">Limbs continue to develop and nails
appear on the digits. The moving
limbs can be “seen” on a scan but
movements cannot be felt yet. </span>
</li></ul><h4>Your <a href="http://www.healthhub.sg/live-healthy/986/pregnancy-symptoms"><span style="color:#0000ff;">symptoms</span></a> </h4><p>Your pregnancy hormones will start to
kick in. You may experience morning
sickness, breast tenderness and fatigue. </p><p>
