During the first week of pregnancy, the fertilized egg travels through the fallopian tube. No significant baby growth occurs yet, and the fertilized egg is called a blastocyte at this stage. Some early symptoms may occur due to hormonal changes, including tender breasts, mood swings, fatigue, and constipation. No ultrasound is typically needed in the first week unless undergoing fertility treatments. It's important to start eating a nutritious diet and consult an OB-GYN once pregnancy is confirmed.

1. 1 Week Pregnant: What To Expect?
1 week pregnant: What to Expect?
You need to forget everything you’ve heard about that moment when you
find out you’re pregnant.
Each time you get your period, your body prepares itself for a potential
pregnancy. A lot of complex hormonal changes will go on in your body, in
readiness to support fertilisation in case it happens anytime soon.

2. This is the reason why we count the first day of a woman’s period as a
starting point for the countdown towards the expected date when the baby is
actually due. Although it may seem to not make any sense but including the
first 2 weeks is a standard practice.
In most women, monthly cycles are variable. Therefore, as a result, when
you miss your cycle for the first time, you may not even realize that you are
pregnant. Many women have spoken about how they don’t realize that they
are pregnant even in the 2nd
week of pregnancy and it is completely
normal. The first week of pregnancy is comparatively smooth without any
obvious signs of pregnancy. Then how would one know about it? That is
exactly what our article will brief you on!
Week 1 – Baby’s Growth
During the first week of pregnancy, the egg moves from the ovary and
travels through the fallopian tube. So you don’t see any significant growth in
your baby in the first week. In the first week, the doctor calculates the first
day of your last monthly menstrual cycle and it is from this day that your
nine month (or 40 weeks pregnancy) term is then calculated. This is why the
1st
week is also included in the pregnancy calendar and is important.
There is no actual major development in the baby during this first
week. During this week the baby is called the blastocyte. The blastocyte is
divided into two parts, the external part of which will become the placenta
and the inner part will become the embryo during the 2nd
week of your
pregnancy. In cases, where more than one egg gets fertilized, multiple
zygotes are formed. These zygotes carry 46 chromosomes from both the
parents and these chromosomes determine the baby’s sex and other physical
features. Now isn’t that interesting? Or maybe overwhelming!

3. Week 1 – Size of the baby
There is no detectable baby size in the first week of pregnancy. You may
wonder “why?”. Well, it is because you are only technically pregnant during
the first week. The first week is included in the pregnancy calendar basically
because it’s basis the 1st
day of your last menstrual cycle that the doctor
predicts the EDD, which is the expected due date of the arrival of your little
one. Hence, there is no baby size to know in this 1st
week.
Week 1 – Common Body Changes/symptoms
You will be able to notice some minor body changes from the first week of
pregnancy. These changes are although minor, but they are pretty good
indicators of the “good news”. These discomfort occur due to the hormonal
changes taking place in the body. Though the body changes during
pregnancy vary in every women but we can list out some common changes
that you may experience in your very first week of pregnancy. Tender
breasts. Changes like:
 Mood swings
 Exhaustion
 Constipation
 Gas formation in the stomach
 Morning sickness
 Vaginal bleeding (as your body sheds the uterine lining which
discards last month’s fertilized eggs)
 Lower back pain and cramps
 Bloating
 Tender breasts

4. Your belly at 1 Week of Pregnancy
In the first week of pregnancy, your body sheds the uterine lining with the
last month’s egg and starts forming a uterine lining to hold and protect the
next month’s egg. The egg that may grow into a foetus. But this will not
show up on your belly in the first week of the pregnancy. This is because
your body will release the egg 14 days before the next expected cycle and it
will take another 24 hours for the egg to get fertilised. Hence there would be
no signs on your belly in this first week time.
1 Week – Pregnancy ultrasound
For normal cases of pregnancies, usually there is no ultrasound done in the
first week. In case, you are going through some treatment to get pregnant
then your doctor may advise you to do an ultrasound in the 1st
week. It is to
check for fibroids and follicles in the ovary. The ultrasound will also
determine the thickness of your uterine lining.
New diet for pregnancy
It is better to start eating healthy if you are trying to get pregnant. You must
consume extra protein and calcium for the needs of the growing foetus
during your pregnancy. For your 1st
week pregnancy food, you must include a
lot of dairy products, legumes, sweet potatoes, salmon, eggs, broccoli and
dark leafy vegetables, lean meat, fish liver oil, berries, whole grains, avocado
and lots of water. Basically you have to load your meals up with food that will
supply folate, zinc, calcium, iron, and fiber to your body. In case you are
unable to get these five critical nutrients from the food you eat then you may
just pop in a supplement or a prenatal vitamin, but only after consulting your
doctor. Healthier YOU means a healthy Baby!

5. Tips & Care
It is the first week of your pregnancy and so the joy will obviously follow and
maybe a little anticipation too. Although, it is normal to be in this moment
