Pregnancy Week 5

A complete guide on Pregnancy Week 5

Congratulations! You have made an entry to the Pregnancy Club. If you check your pregnancy via Home Pregnancy Test Kit, you will see those two pinks lines, which indicates a positive result.

At this time, your baby has grown to the size of an apple seed from a poppy seed. During the 5th week of pregnancy, hCG (human Chorionic Gonadotropin) levels are quite enough to show you a positive result of your pregnancy. Moreover, the symptoms get more visible and strong.

The first trimester is considered to be crucial for pregnancy, so being in the 5th week of pregnancy, you should know about your fetal development, your moods and accompanied symptoms and what you should do and what not.


During the 5th week of pregnancy, your baby is tiny and looks like an orange seed or an apple seed, and measures around 0.13 inches. At this stage, your baby is known by the term 'embryo', which has three layers - the ectoderm, the mesoderm and the endoderm. These layers further develop into various body parts. The top layer, the ectoderm, is responsible for the development of a baby's brain, spinal cord, nerve, and backbone. Whereas, the mesoderm layer develops the circulatory system and the heart of a baby. And the endoderm, which is the innermost layer gives rise to the stomach, the liver, the intestines, the lungs and the pancreas. By the 5th week of pregnancy, your baby's heart will split into two chambers which will be responsible for beating and pumping the blood.

Moods and Symptoms

The pregnancy symptoms at the 5th week are more visible and strong. Although, there have been several cases in pregnancies wherein a woman did not experience any symptoms. Hence, pregnancy can be different from woman to woman. However, it is rightly said that the first trimester of the pregnancy is comparatively tougher than the rest two if it is been handled carefully, it passes easily without any worries.

Some commonly experienced pregnancy symptoms are:

Tender and sore breasts - This is one of the most common and early symptoms of pregnancy. You may feel some kind of pain and tenderness even with the gentle touch to your breasts. This tenderness happens due to the increase in hormone levels which causes your breasts to stretch and expand.

Morning Sickness - It is the feeling of nausea accompanied by vomiting. It is an unpleasant feeling that makes the person tired. Due to the increased level of hormones and reduced blood sugar, morning sickness occurs. Although this symptom continues for the first trimester of pregnancy, you can manage morning sickness with some useful tips.

Frequent urination - Frequent urination is one of the early pregnancy symptoms. During the whole pregnancy, the levels of the hormone change and fluctuates, and so this happens during the first trimester of the pregnancy as well, which results in frequent urination. The change in hormone levels stimulates kidney functions which help to release waste from your body more frequently.

Cramps - You may experience some cramps and light spotting as the embryo implants itself in the uterus. This is absolutely normal and there is nothing to worry about.

Mood Swings - Mood swings are quite unpleasant but as the body is not in its regular phase, mood swings are pretty normal. However, as you move on to the second trimester you may feel better.

Do's and Don'ts

The first trimester of the pregnancy gives several doubts and confusion in mind. Hence, it is essential to follow some dos and don'ts to rule out any doubt or any confusion.
