Experiencing pregnancy symptoms before a missed period can be a common occurrence for some individuals. These symptoms can vary from person to person and from one pregnancy to another. 

Typical early signs of pregnancy

Here are some of the typical early signs of pregnancy that may be observed before a missed period:

Missed or lighter menstrual periods

For those with regular monthly menstrual cycles, a missed period is often the earliest and most reliable indication of pregnancy. In some cases, during the first few weeks of pregnancy, there might be a light bleed similar to a period, accompanied by spotting or minimal blood loss, known as implantation bleeding.

Morning sickness and nausea

Nausea and vomiting, commonly referred to as "morning sickness," can occur at any time of day or night, not just in the morning. These symptoms usually begin around 4 to 6 weeks into pregnancy. If you experience severe and persistent vomiting, it's essential to see a GP as it may be a sign of hyperemesis gravidarum (severe morning sickness), and it requires immediate medical attention.

Fatigue and exhaustion

Feeling tired or exhausted, particularly in the first 12 weeks of pregnancy, is normal. Hormonal changes during this period can lead to feelings of fatigue, sickness, emotional fluctuations, and distress.

Breast sensitivity

Early pregnancy may cause your breasts to feel tender and become larger, similar to sensations before your regular period. You might also experience tingling sensations, increased visibility of veins, and darkened and more prominent nipples.

Frequent urination

An increased need to urinate, including during the night, can be an indication of pregnancy. This occurs due to the higher volume of blood circulating in your body during pregnancy. As your body prepares to nurture the developing fetus, your blood supply rises, and your kidneys work to filter the increased blood volume, eliminating extra waste products. This excess waste is expelled from your body as urine, causing you to feel the need to pee more frequently. The more blood your body contains, the greater the urge to urinate.

Other pregnancy signs to observe

Apart from the mentioned symptoms, there are other indicators of pregnancy to be aware of, such as constipation and an increase in vaginal discharge without any soreness or irritation.1


Spotting, also known as implantation bleeding, may cause concern, but it can actually indicate that an embryo has successfully implanted in the lining of your uterus. This process typically occurs around 10 days after conception. Implantation bleeding appears as small drops of blood or as a brownish discharge from your vagina. It might coincide with your regular period and can last from a few days to a few weeks. This can sometimes be mistaken for a light period, leading some individuals to believe they are not pregnant.

Food cravings

Early pregnancy can bring about various changes in food preferences and cravings. Some might experience food cravings and constant hunger, while others may develop food aversions, causing certain foods or flavours to suddenly become unpleasant, even if you had enjoyed them before.

Metallic taste

One common symptom during the early stages of pregnancy is a metallic taste in the mouth, often likened to having a pile of coins in the mouth. This sensation can be triggered by eating certain foods and can occur randomly throughout the day.


Headaches, dizziness, and lightheadedness are also common occurrences due to the hormonal changes and increased blood volume during early pregnancy.1


Mild, period-like cramps and pelvic pain that come and go over a few days are other symptoms some may experience.1 However, severe cramps felt mainly on one side of the body require immediate attention from a healthcare provider, as they could be a sign of an ectopic pregnancy (it is when a fertilised egg is implanted on the outside of the womb) or other complications.

Mood swings

Mood swings are a normal part of pregnancy as hormones continue to fluctuate. However, if feelings of anxiety, depression, or self-harm arise, seeking support from a healthcare provider is essential.

Stuffy nose

During early pregnancy, congestion and a stuffy nose may occur due to elevated hormone levels and increased blood flow. The mucous membranes in the nose may dry out, leading to potential bleeding.


The surge of hormones can also cause bloating and increased gas in the stomach, even before a noticeable baby bump develops.

Changes in the skin

Changes in the skin, such as acne or other variations, can be attributed to the increased hormone levels and blood volume during pregnancy. Some may experience a pregnancy glow and clearer skin, while others may face the challenge of more frequent pimples.

Remember, these signs can vary in intensity and onset from person to person and from one pregnancy to another. Some of these symptoms are similar to the symptoms you might experience before your period, but if you suspect you might be pregnant or experience any concerning symptoms, seek professional medical advice to ensure a healthy pregnancy journey.


When do pregnancy symptoms typically begin?

The onset of pregnancy symptoms varies among individuals. Some may experience them within a few days of conception, while others may not feel pregnant until several weeks after receiving a positive pregnancy test. The timing and intensity of pregnancy symptoms can differ not only from person to person but also between pregnancies.

Is it possible to experience pregnancy symptoms before missing a period?

Yes, it is possible to feel pregnant before missing a period. Some individuals report experiencing pregnancy symptoms as early as one week after conception, which is about a week before their expected period.

Could early pregnancy symptoms be present even if I am not pregnant?

Yes, early pregnancy symptoms can sometimes be similar to symptoms of other medical conditions or normal premenstrual symptoms. This can make it challenging to differentiate between pregnancy and other factors. Additionally, factors like significant weight changes, stress, or breastfeeding can also cause missed periods. To confirm pregnancy, it is best to take a pregnancy test, which can be purchased without a prescription at local pharmacies or grocery stores.

When is the earliest I can take a pregnancy test?

Pregnancy tests work by detecting the presence of human chorionic gonadotropin (hCG) hormone in urine. This hormone is released by the placenta during pregnancy. You can take a pregnancy test as soon as you have missed your period. However, for the most accurate results, it is advisable to wait at least one week after the missed period before taking the test. Some tests claim to provide accurate results before a missed period, but testing too early might lead to a false negative result.

In some cases, healthcare providers can perform a blood test to detect pregnancy as early as one week before a missed period.

When should I contact my doctor after a positive pregnancy test?

If you have missed your period and received a positive pregnancy test, your next step should be to contact your healthcare provider to schedule your first prenatal appointment. During this appointment, your healthcare provider may inquire about your prenatal vitamin intake, particularly those containing folic acid. Folic acid is crucial in early pregnancy as it aids in the development of the fetal neural tube, which eventually becomes the baby's brain and spine. Many healthcare providers recommend taking folic acid for anyone who could become pregnant.

If you are planning a pregnancy, it is advisable to have a preconception appointment with your healthcare provider. This appointment is especially important if you take medication for a chronic illness or have medical conditions like diabetes, high blood pressure, or lupus. Your healthcare provider will review your current medical conditions and general health before pregnancy, ensuring you are in the best possible condition for a new pregnancy.


Experiencing pregnancy symptoms before a missed period is common for some people. Early pregnancy signs include missed or lighter menstrual periods, morning sickness and nausea, fatigue, breast sensitivity, frequent urination, constipation, and increased vaginal discharge. Other symptoms that some might experience include spotting (implantation bleeding), food cravings or aversions, metallic taste in the mouth, headaches, mood swings, congestion, bloating, changes in the skin, and mild cramps. These symptoms can vary in intensity and onset from person to person and from pregnancy to pregnancy. Pregnancy symptoms can start as early as one week after conception, and it's possible to take a pregnancy test as soon as you miss your period for the most accurate results. You might experience some of these symptoms when you're getting sick or when your period is about to start. It is important to seek professional medical advice if you suspect you might be pregnant or experience any concerning symptoms to ensure a healthy pregnancy journey.
