Guide on Pregnancy Week 4

Welcome to the beginning of pregnancy!

Four weeks of Pregnancy = 1 month of pregnancy

Week 4 pregnancy indicates the beginning and the starting point of embryo development. It is an implantation stage, wherein the blastocyst settles in the uterus lining and split to form the placenta and the embryo.

Fetal Development

The size of your baby is 1mm and is like a poppy seed. During this week, an amniotic sac will start forming around it. The Amniotic Sac, commonly called a bag of water, protects the baby in the womb and helps it to grow and develop. Until the 10th week, many organs of your baby will develop while some of them will start functioning too.

Three distinct layers of cells grow to form the different parts of your baby’s body. The endoderm layer (inner layer) transforms into digestive systems, lungs, and liver. The mesoderm layer (middle layer) transforms into your baby’s heart, genitals, kidneys, muscles, and bones. And the outer layer which is called an ectoderm layer gets transformed into your baby’s hair, eyes, and skin.

Moods & Symptoms

During the 4th-week of pregnancy, your body changes and show discomfort. The common symptoms during the fourth week of pregnancy are as follows:

  • Implantation Bleeding – As the blastocyst attaches to your womb, many women reports implantation bleeding. This type of bleeding is light in colour and stays for a shorter time period. Sometimes, it is only spotting, which is often mistaken with regular periods.

  • Bloating – This is due to the change in your hormones. You may feel a little bloated near your abdominal area.

  • Mood Swings – During pregnancy, there is a big change in hormone levels, which results in mood swings. Mood swings are nothing but rapid or extreme change in the mood. Talk to your gynaecologist for seeking better help in dealing with mood swings.

  • Mild cramps – Mild cramps are a clear indication of implantation. However, they are totally normal, still, if you feel severe cramps then you may speak to your doctor.

  • Morning sickness – It is one of the most common symptoms during the first trimester of pregnancy. Morning sickness comes in a form of vomiting, and nausea.

  • Fatigue – You may feel like you get tired very quickly nowadays. Just a minor daily work lets you feel more tired and fatigued.

  • Tender breasts – Your breasts may be extra tender and sore due to the surge in the hormone which is retaining more fluids and feeling heavy.
