There are many symptoms you may feel throughout pregnancy. None of these symptoms, however, can be felt on the first day. This is because, technically speaking, the first day of pregnancy is actually the day you conceive your baby. That said, you might experience pregnancy symptoms as early as the first day of your missed period. Tiredness, breast tenderness, increased need to urinate, nausea and vomiting, change in smell sensitivity and light vaginal bleeding are among the earliest symptoms of pregnancy.


Tiredness is often one of the first symptoms of pregnancy, and it may persist beyond your first trimester. You may be more tired in the morning upon waking, need to go to bed earlier at night or feel you need to nap to make it through the day. If you are anemic or have low levels of other key nutrients, you may feel even more tired.

Breast Tenderness

Breast tenderness is another common early symptom of pregnancy. This can occur as soon as your first missed period. Your breasts may also be more sensitive to touch and tender or achy. You may find wearing a bra or sleeping on your stomach uncomfortable.

Increased Urination

Many women feel the need to pass urine more frequently early on in pregnancy. This can occur both during the day and at night, meaning you need to get up when asleep to go pass urine. The need to pass urine more often in early pregnancy may relate to hormone changes.


Spotting, or small amounts of bleeding through the vagina, early in pregnancy may be due to hormone changes related to the pregnancy implanting -- or taking hold -- inside the uterus. Shedding small amounts of your uterine lining when the fetus implants may also contribute to minor vaginal bleeding. Spotting in early pregnancy usually consists of only a small amount of bleeding and is unlikely to contain significant clots.

Morning Sickness

Nausea and vomiting during pregnancy is commonly referred to as morning sickness -- although it can occur at other times of day. An article published in "Obstetrics and Gynecology" in May 2000 states that nausea and vomiting affect between 50 percent and 70 percent of women in early pregnancy. These symptoms can start as early as 4 weeks into your pregnant. The nausea of early pregnancy is thought to be due to hormone changes. While all pregnant women have these hormone changes, not everyone experiences morning sickness.

Increased Sensitivity to Smell

A study published in "Chemical Senses" in March 2014 found that 67 percent of respondents reported increased sensitivity to smell from early on in pregnancy. Change in smell sensitivity can lead to food cravings -- smelling enticing food can make you desire it more. It can also lead to food aversion. The aroma of certain foods may be off-putting in pregnancy, and you may no longer wish to eat them due to the smell alone. Certain smells can also contribute to morning sickness. Simply smelling a food you no longer like can make you feel nauseated.

When to See Your Doctor

Medical care is important throughout pregnancy, so schedule an appointment to see your doctor if you think you may be pregnant. Other reasons to contact your doctor in early pregnancy include:
-- extreme fatigue and sluggishness.
-- severe morning sickness.
-- breast tenderness in one spot.
-- nipple discharge, unusual tethering of your breast skin or a breast lump that concerns you.
-- burning with urination or blood in your urine.
-- heavy vaginal bleeding or passing clots.
