Calculate your due date

Seems a bit confusing, but calculating your due date is not that hard. Here are few points to consider:

  1. Remember the first day of your last menstruation cycle.
  2. It will be best to remember how many days your menstruation cycle last or after how many days your period returns. Most cycle lengths are 21 days
  3. The sperms can stay in your body for up to six days which means that the day of the intercourse does not usually count for the day of the conception.
  4. You won’t even notice any change in your body for the first 4 weeks until you miss your period and the hCG levels grow which ultimately results in a positive pregnancy test.
  5. You are already 5 weeks pregnant by the time your pregnancy test comes positive.
  6. Your ideal due date will be between 38 to 42 weeks

The common due date thumb rule is 40 weeks from the first day of your last menstruation cycle.

So just take the first day of your last period and calculate 40 weeks from that day. You will have your probable due date. Let’s say that your last period started on 1 January 2020, your due date will be the 30th of September 2020.

Only 5 percent of the babies are born on their exact due date. So do not depend on your due date. Your baby may come early as 38 weeks or as late as 42 weeks.

How many months are 5 weeks?

At 5 weeks, you are in the last week of your first month. You will be starting your second month from next week. You’re 35 weeks or 8 months away from delivering your happy and healthy baby.

Baby Development at week 5

Developing a baby is a hard task. It calls for extra and hard work to grow a healthy baby. All the organs and systems of the baby will form the base zero. Everything will be shining new. It is the starting point when a baby’s essential systems and structures will develop. 

It is also known as the Embryonic period. First comes into action, the process of differentiation when cells multiply and divide to form different structures and systems.

How big is the baby at week 5?

At 5 weeks, your baby is as big as a sesame seed or a strawberry seed with a tiny tail right now. Your baby measures around 1.5 mm.

Cell Formation

As the three most essential groups of cells; ectoderm, endoderm, and mesoderm come into play, this week, the ectoderm focuses on forming the neural tube which will the base for your baby’s brain and spinal cord. Whereas the mesoderm focuses on forming the blood circulatory system and then the main component of this system; The heart.

The heart of your baby

The tiniest little heart of your baby at 5 weeks is made up of two channels known as the heart tube. These heart tube will combine to form a fully functioning heart of your baby. You will be able to hear the heartbeat of your baby by the mid of this week and later.

As soon as the doctor confirms the heartbeat of your baby, you can invest in a fetal Doppler which is a handheld device you can easily use at home to listen to the heartbeat of your baby.

You might not be able to see the heart in the ultrasound at week 5, but will be commonly visible during the 6th or 7th week.

Your Belly at week 5

You might not be able to feel anything at this point other than just feeling a little bloated. Your uterus is just the size of a small orange seed. In just a couple of months, you will begin to see some visible growth and changes in your body.

Pregnancy Symptoms

Your body is working so hard to create a baby-friendly environment in your body. Several early pregnancy signs have started to show up and escalate. Your body is producing large quantities of pregnancy hormones; hCG, progesterone, and estrogen. 

These hormones will drive fatigue, exhaustion, morning sickness, tender breasts, metal taste buds, indigestion, congestion, etc.

Fun fact: Pregnant women experience a heightened sense of smell especially during the first few weeks up to the end of the first trimester, this somehow helps in avoiding unsafe food that they might eat.

These hormones might be driving you crazy by causing all those annoying PMS like pregnancy symptoms, but they are very important for your baby.

  • Estrogen keeps the required levels of hCG and progesterone.
  • Progesterone maintains the functions of the placenta, stimulates the breast’s tissue growth to prepare your breasts to soon be a milk making machine, keeps the uterus calm and smooth so the muscles of the uterus do not contract as it may cause the uterus to lose its lining leading to an early miscarriage.
  • HCG takes care of the follicle which developed, ovulated, and ruptured the embryo, also called the corpus luteum, to keep producing the estrogen and progesterone until the placenta is completely developed at about week 10.

What to avoid at week 5

Eat healthy and fresh produce and avoid the following as they may increase the risk of harm to you and your baby.

  1. Any food that is raw or uncooked
  2. Fish that contain mercury like shark, mackerel, swordfish, shellfish
  3. Anything that has high levels of vitamin A e.g. liver
  4. Alcohol or drug use
  5. Overdosage of caffeine. More than 200mg is excessive and considered harmful to your baby

When to call a doctor

Take extra care of yourself and your baby as the first trimester (week 1-12) is the most vulnerable time. You and your baby are at harmful risk from a lot of things.

Alert your doctor or ob-gyn if your experience heavy bleeding, fever, severe pelvic cramps, shoulder pains accompanied by chills or dizziness. Also, let your doctor know if you suffer pain or burn when urinating. The doctor will check for Urinary Tract Infections (UTIs).
