Emotional Changes You May Experience

The well-known "glow" of pregnancy might have something to do with how pleased expectant women feel. The early weeks of your pregnancy are a time to relish; a time when you can feel justifiably proud of the miracle that has taken place. Other emotions may be:
  • Irritability
  • Mood swings
  • Weeping
  • Fear, joy, elation; any or all of these
Be Alert to Warning Signs

Call your doctor if you experience any of the following:
  • Vaginal bleeding
  • Fainting spells
  • Severe nausea and vomiting
  • Chills or fever over 100 degrees
How Is My Baby Growing?

Your baby, called an embryo at this stage, is smaller than a grain of rice. The heart begins to beat at day 25.
