When can a woman be called pregnant?

A woman becomes pregnant when the fertilized egg gets implanted in the uterus. It ends through either spontaneous or elective abortion or delivery. During this time, the mother’s body goes through immense changes involving all organ systems to sustain the growing fetus. These changes may find a manifestation through the various symptoms and signs of pregnancy. [1]

Early signs of pregnancy

  1. Missed Period: A missed period, which is the absence of menstrual bleeding, is often the first and most noticeable sign of pregnancy. It occurs when the fertilized egg implants itself in the lining of the uterus, initiating the hormonal changes necessary to support pregnancy. [3]
  2. Breast Changes: During early pregnancy, hormonal fluctuations lead to various changes in the breasts. This may include breast tenderness, swelling, and increased sensitivity. The breasts may feel fuller, heavier, and more sensitive as they undergo preparations for future milk production and breastfeeding. These changes are a result of increased blood flow and hormone stimulation in the breast tissue. [3]
  3. Fatigue: Feeling unusually tired and exhausted is a typical early pregnancy symptom. The body goes through significant hormonal changes, leading to fatigue and an increased need for rest. [3]
  4. Nausea and Morning Sickness: Nausea, often accompanied by vomiting, is a well-known symptom of pregnancy. It is commonly referred to as morning sickness, although it can occur at any time of the day. [2] [3]
  5. Frequent Urination: Increased blood flow and hormonal changes cause the kidneys to produce more urine, leading to more frequent trips to the bathroom. [3]
  6. Food Cravings and Aversions: Many women experience strong cravings for certain foods and may develop aversions to foods they previously enjoyed. These cravings and aversions are influenced by hormonal fluctuations. [7]
  7. Mood Swings: Hormonal changes during pregnancy can cause emotional ups and downs. Women may experience heightened emotions, irritability, and mood swings. [8]
  8. Increased Basal Body Temperature: Monitoring basal body temperature can indicate pregnancy. A sustained increase in body temperature beyond the expected duration of the menstrual cycle may be a sign of pregnancy. [4]
  9. Heightened Sense of Smell: Pregnant women often have a heightened sense of smell, and certain odours may trigger nausea or aversions. [9]
  10. Constipation: Hormonal changes can slow down the digestive system, leading to constipation during pregnancy. It is important to maintain a healthy diet and stay hydrated to alleviate this symptom.
  11. Dizziness and Fainting: Low blood pressure and increased blood volume can cause dizziness and fainting spells. It is important to get up slowly from a sitting or lying position to avoid sudden drops in blood pressure.
  12. Bloating and Gas: Hormonal changes can lead to bloating and excess gas in the digestive system, causing discomfort and a feeling of fullness.
  13. Headaches: Some women experience headaches during early pregnancy due to hormonal changes and increased blood flow. [10]
  1. Backache: As the body adjusts to pregnancy, the ligaments and joints loosen, which can cause back pain and discomfort. [6]
  2. Spotting or Light Bleeding: Light bleeding or spotting may occur during early pregnancy, often mistaken for a light period. This is known as implantation bleeding and occurs when the fertilized egg attaches to the uterine lining. [5]

How early do pregnancy symptoms start?

The early signs of pregnancy may appear within one to two weeks after conception for many women. But in most cases, the symptoms become more evident and pronounced only after seven weeks from the day of conception. [11] [12]

When to consult a doctor about the new pregnancy?

You must usually go for a doctor consultation around 8 weeks gestation. However, women who have diabetes or high blood pressure problems must consult a doctor as early as possible. The same applies to women with any other such medical condition. Early detection and confirmation of pregnancy in the case of these women can help avoid complications later. So, for these women, it is advisable to see a doctor as soon as they miss their periods.


1. Can a home pregnancy test kit give false-negative results?

Yes, it can.  This usually happens when you take the test too early.

2. Are pregnancy symptoms the same for everyone?

No, pregnancy symptoms can vary from woman to woman. Some may experience many symptoms, while others may have few or none at all.

3. Can pregnancy symptoms be similar to premenstrual symptoms?

Yes, many early pregnancy symptoms are similar to premenstrual symptoms. However, certain symptoms like missed periods and positive pregnancy tests can confirm pregnancy.

4. Is it possible to have no symptoms and still be pregnant?

Yes, it is possible to be pregnant and have no noticeable symptoms. Every woman’s experience is different, and some may have a relatively symptom-free pregnancy.

5. How soon can I take a pregnancy test?

You can take the test on the very first day of a missed period. In case you are not aware of the due date of your next period, you need to take the test at least 21 days after the last unprotected sex you had.


In conclusion, recognizing the early signs of pregnancy is crucial for women who are trying to conceive or suspect they may be pregnant. While the mentioned symptoms are common, it’s important to note that they can vary from person to person. If you suspect you may be pregnant, it is always best to consult with a healthcare professional for confirmation and guidance throughout your pregnancy journey. Embrace the miraculous experience of pregnancy and prioritize your well-being and the health of your growing baby.
