While most women are aware that missing a menstrual cycle is the first sign that you might be pregnant, many are not aware of the other early signs of pregnancy. While a home pregnancy test (or a visit to your doctor) is the surest way to confirm that you're pregnant, there are other signs that you can look for if you suspect you may be expecting.
Vomiting or Nausea
Nausea is common as early as two weeks after conception. Commonly known as "morning sickness," it can occur any time of the day. Believed to be caused by higher levels of estrogen combined with heightened senses, nausea typically subsides by the end of the first trimester but in some cases continues throughout the pregnancy.
Fatigue
In the first stages of pregnancy, levels of the hormone progesterone rise significantly as the body begins to build the placenta; high levels of progesterone can cause fatigue (as well as constipation). According to the Mayo Clinic, in the first few weeks of pregnancy blood pressure is lower, blood production is increased and blood sugar levels drop; all contributing to a feeling of tiredness. Some women also experience faintness or dizziness, for the same reasons.
Changes in Nipples or Breasts
Breast changes may be the first signal of pregnancy, as the change in hormone levels may make the breasts or nipples sore, tingly or tender. The breasts may also feel heavier or fuller. Some women notice a darkening of the areolas, as the breasts prepare for the production of milk.
Moodiness and Headaches
The National Institute of Child Health and Human Development states that moodiness is common in the first stages of pregnancy as the body produces an abundance of hormones. Many women experience unexplained bouts of weeping and mood swings as their bodies attempt to adjust to the new hormone levels. Mild headaches are common early in pregnancy, as hormonal changes increase the circulation of blood.
Spotting Blood
Some women experience a small amount of vaginal bleeding 10 to 14 days after fertilization. Lighter and spottier than a normal menstrual period, this type of bleeding doesn't last as long as a period. Sometimes this "implantation bleeding" is accompanied by cramping that is similar to menstrual cramps.
Craving Foods
Some women experience cravings (or aversions) for certain foods, especially during the first trimester of pregnancy. Likewise, she may experience a heightened sense of smell and taste; as with other early pregnancy symptoms this is attributed to the drastic rise in hormones.
