By week 5 of pregnancy, rising hCG hormone levels mean a home pregnancy test will likely show a positive result, while the embryo — no larger than an orange seed — is already developing a beating heart and neural tube that will become the brain and spinal cord. Common symptoms at this stage include nausea, fatigue, breast tenderness, and frequent urination, all driven by surging progesterone and oestrogen. Notably, morning sickness is associated with a reduced risk of miscarriage. Broccoli is highlighted as an especially valuable food at this point, delivering folic acid to help prevent neural tube defects such as spina bifida, alongside calcium, iron, Vitamin C, and antioxidants that support placental circulation and embryonic development.
- At week 5 of pregnancy, the baby's circulatory system and heart are actively developing, with the heart beginning to beat visibly on an early ultrasound.
- The embryo at week 5 resembles a tiny tadpole and is approximately the size of an orange seed.
- The neural tube begins to develop at week 5 and will later form the baby's spinal cord and brain.
- The brain at this stage divides into 3 primary sections: the forebrain, hindbrain, and midbrain.
- Morning sickness, though uncomfortable, is considered beneficial because it reduces the risk of miscarriage.
- Broccoli is highlighted as a key pregnancy superfood, supplying Vitamin C, Vitamin A, folic acid, calcium, iron, Vitamin K, B vitamins (B1, B2, B3, B5, B6), and omega-3 fatty acids.
- Folic acid found in broccoli specifically reduces a baby's risk for neural tube defects such as spina bifida.

Pregnancy Diary Week 5: How Is Your Baby Growing?
At this point in time, your baby’s circulatory system and heart are developing. Your baby now looks like a tiny tadpole with a tail. It’s size could be as small as the seed of an orange. The embryonic tissues are forming rapidly into a heart. The heart begins to become functional and through an early ultrasound, you might be able to see it beating.
The neural tube also begins to develop. Later on, it will form into the baby’s spinal cord and brain. The brain develops into three primary sections, the forebrain, hindbrain and midbrain and each has its own corresponding functions later on.
What you can expect
Pregnancy symptoms such as frequent urination, breast tenderness, nausea, vomiting, fatigue, excessive saliva, food aversion and food cravings are more likely to be experienced. Morning sickness should be expected but of course, there is a benefit in the occurrence of this universal symptom. It reduces your risk for miscarriage.
Excessive saliva, nausea and vomiting should be blamed to those pregnancy hormones. Nausea and vomiting can be controlled by maintaining a healthy diet. Never attempt to skip meals as it can trigger nausea and vomiting.
At this stage, many pregnant women start to develop cravings for certain types of foods. In some cases, pregnant women tend to develop a particular liking to combinations of certain foods. On the other hand, some pregnant women tend to dislike foods which in normal circumstances, they would love to eat. This phenomenon can also be blamed on your hormones.
The emotional and hormonal changes during this period may require an additional amount of energy. The body is working hard due to the changes that are taking place inside plus dealing with the surge of pregnancy hormones. In effect, fatigue can be expected.
Progesterone and oestrogen should also be blamed for the tender and ultra-sensitive sensations in your breasts. Also, there is an increased flow of blood to your breasts which help your breast turn into machines that produce milk. Increased and frequent urination should also be expected. There is also an increase in the flow of blood to your kidneys and pelvic area to make them more efficient during this stage.
Broccoli For Pregnancy Nutrition
Broccoli is definitely one of the most nutritious foods to eat during pregnancy. It is part of the cabbage family which is loaded with essential vitamins and minerals that offer profound health benefits.
It is a cruciferous vegetable fortified with Vitamin C, Vitamin A and folic acid which are scientifically proven to be beneficial in optimising baby’s health. Broccoli is also an excellent source of calcium, folate, Vitamin K, Vitamins B1, B2, B3, B5 and B6 as well as manganese, tryptohphan, phosphorous, magnesium, potassium, protein, iron, zinc, calcium and omega 3 fatty acids.
Its calcium and iron content is beneficial in preventing the development of osteoporosis as it helps in the process of bone formation. Meanwhile, its Vitamin C content safeguards pregnant women from having common colds. Broccoli is also rich in folic acid which reduces your baby’s risk for neural tube defects like spina bifida. On the other hand, its iron content is beneficial in increasing the volume of your blood. An insufficient amount of iron in the body can increase your risk for anemia.
Eating broccoli at this stage reduces your baby’s risk for birth damages. This cruciferous vegetable contains high level of antioxidants which are beneficial in promoting efficient blood circulation into the placenta. It also facilitates in the sufficient and efficient distribution of nutrients and oxygen to the baby’s brain. It even helps in protecting the embryo against micro-traumas.

What pregnancy symptoms are common at 5 weeks?
At 5 weeks pregnant, common symptoms include frequent urination, breast tenderness, nausea, vomiting, fatigue, excessive saliva, food aversions, and food cravings. These symptoms are largely caused by the surge of pregnancy hormones such as progesterone and oestrogen.
Why does morning sickness occur during early pregnancy?
Morning sickness is caused by pregnancy hormones and is considered a universal symptom of early pregnancy. It is associated with a reduced risk of miscarriage, and nausea and vomiting can be managed by maintaining a healthy diet and avoiding skipping meals.
Can you get a positive pregnancy test at 5 weeks?
Yes, at 5 weeks a pregnancy test is more likely to show two lines because hCG hormone levels in the body have increased enough to be detected. A positive result at this stage is a reliable indicator of pregnancy.
Why do pregnant women experience fatigue at 5 weeks?
Fatigue at 5 weeks occurs because the body is working hard to accommodate the physical and hormonal changes of early pregnancy. The emotional demands of the surge in pregnancy hormones also require additional energy, contributing to tiredness.

Its folic acid content helps reduce the baby's risk of neural tube defects such as spina bifida, and its iron content supports healthy blood volume in the mother.
What organ systems develop in a baby at 5 weeks pregnant?
At 5 weeks, the baby's heart and circulatory system are actively developing, with embryonic tissue forming into a functional heart that may be visible beating on an early ultrasound. The neural tube also begins forming and will later develop into the baby's brain — divided into the forebrain, midbrain, and hindbrain — and spinal cord.
Why do pregnant women experience breast tenderness at 5 weeks?
Breast tenderness at 5 weeks is caused by the hormones progesterone and oestrogen, along with an increased flow of blood to the breasts. This increased blood flow is part of the process by which the breasts begin preparing to produce milk.
