4 Weeks Pregnant – Early Pregnancy Symptoms Explained

4 Weeks Pregnant – Early Pregnancy Symptoms Explained

Many congratulations! We understand your excitement as you just missed your period and instead of waiting for some time, you took the test. Voila! Two pink lines have changed your life, like never before.

At a time when you are used to the idea of having a baby, we totally understand your excitement, happiness, anxiety and nervousness. But having said that, you may not feel a lot different at this stage of 4 weeks pregnant as the pregnancy symptoms have not kicked in their full-blown capacity.

Do you know, right now, as we speak when you are 4 weeks pregnant, your baby is even smaller than a poppy seed? Yes, believe it or not, but the baby right now is practically microscopic. In scientific terms, the baby at 4 weeks of pregnancy is called blastocyst – a small ball of cells which is busy settling into your uterus, his/her new home. While doing that, your body is also preparing itself for major physical changes and developments that will occur in the next 9 months or so.

4 week pregnant

At 4 weeks of pregnancy, you might not experience many symptoms that are associated with pregnancy. But brace yourself, because pregnancy hormones increase pretty quickly. Therefore, it is absolutely normal to be 4 weeks pregnant with no or very few pregnancy symptoms. However, you can expect these pregnancy symptoms in the fourth week.

4th Week Pregnancy Symptoms

Missed period

One of the earliest signs of pregnancy, a missed period always raises an alarm. It shows that the progesterone hormone levels are going to take over your hormonal balance. This would aid is sustaining the pregnancy.

Breast tenderness

Yes, your tender and swollen breasts would hurt screaming, ‘the baby is coming. Start producing milk!’. To provide comfort to the breasts, go for supportive bras. Your breasts need good care and attention at this stage.


Feeling puffed up all the time? Your ‘culprit’ is the pregnancy hormone, progesterone. We suggest you switch to loose and comfortable clothes to avoid discomfort.


You might experience uncomfortable pregnancy in the fourth week of pregnancy. But worry not. This is actually a good sign that your baby has implanted properly on your uterine wall. But, in case you experience severe cramping that does not go away, consult your doctor for further examination to rule out any kind of complication.

Mood swings/temperamental

No, it is not a figment of your imagination. You might be acting differently than your normal reaction. This is because of the fluctuating pregnancy hormones. This is one of the most drastic symptoms of early pregnancy.

Relaxation is very important to keep the volatile mood swings at a bay. It is important to know that these changing moods settle after the first trimester as the hormones level out in due course of time.

Morning sickness

Almost 50-90 percent of pregnant women experience morning sickness in the form of nausea and/or vomiting. You might experience this in the fourth week of pregnancy or even in later stages. It is a symptom that slowly gets better and vanishes by the end of the second trimester.


Feeling exhausted most of the times? Well, it is a bit natural owing to the extra work your body is performing at this stage. Remember we told you about Blastocyst? That small ball of cells is now growing into an embryo and your body is working extra hard for that resulting in fatigue and tiredness.

Taking care of yourself is often overlooked by new moms-to-be. You must ensure that you give yourself sufficient rest, care and attention to avoid physical and mental exhaustion.

A small nap in the afternoon and/or light exercise (with consultation with the doctor) can be helpful in giving that extra dose of energy to your new pregnant body.


Mild spotting in the fourth week, also known as implantation bleeding is quite common in the fourth week of pregnancy. But if you notice unusual bleeding (bleeding like a period lasting for more than 2 days) consult your doctor without any delay.

In the coming weeks, the pregnancy hormones are going to increase. However, your body will adapt to the new changes making your pregnancy journey comfortable and memorable. What you need to remember at this stage is some basic yet important points:

  • Do not miss your prenatal vitamins
  • Quit smoking and drinking
  • Rest adequately
  • Pamper yourself
  • Avoid stress – physical as well as mental
  • Make your first prenatal appointment

Pregnancy is a beautiful journey. Cherish it as it is going to make you not beautiful, but also stronger and fitter. The only prerequisite for that is you must take care of yourself and enjoy this amazing phase.
