When it comes to pregnancy, not all women experience the same symptoms at the same stage. The earliest symptom of pregnancy can vary, depending on the individual. The first symptoms often start showing up within just a few weeks of conception, often around the time of the first missed period. A positive pregnancy test can help confirm your suspicions.
Breast Changes
One of the most common symptoms of early pregnancy involves your breasts. Within the first two to three weeks following conception, you may notice your breasts begin to feel fuller and heavier. Your changing hormones can cause your breasts to appear swollen and feel sore, tender or tingly. These changes in your breasts are usually the most noticeable symptoms during your first pregnancy.
Bleeding
A missed period signals the first symptom of pregnancy for many women, although about 25 percent of women experience some vaginal bleeding or spotting during pregnancy, according to the University of Maryland Medical Center. Implantation bleeding can occur about 10 to 14 days after fertilization. Some women mistake this type of bleeding for a menstrual period, although the bleeding is usually lighter and shorter than an average period. As your uterus begins to enlarge, you may also experience cramping that resembles menstrual cramps.
Digestive Changes
Most women experience some feelings of sickness during early pregnancy, usually between the fourth and eighth weeks of pregnancy. Slight queasiness may follow conception by as little as two weeks. This type of nausea may occur at any time of the day, not just in the morning. Certain factors can contribute to this uncomfortable symptom, including the smell of food, cigarette smoke and perfume. You may also experience an aversion to certain foods, including those you normally enjoy. Increased amounts of progesterone can slow down your digestion, possibly leading to constipation.
Fatigue
Most women experience symptoms of fatigue, especially during the initial phase of pregnancy. Feelings of tiredness often occur in the first few weeks of pregnancy, due to an increase in hormones and blood volume. High levels of progesterone can increase feelings of fatigue that tend to sap your energy. Circulatory changes can make you feel dizzy or faint. These sensations may occur in response to dilated blood vessels or low blood sugar.
