Nausea is a common sign of early pregnancy.

At this stage, there are still few, if any, visible physical body changes for you.

However, your baby needs more and more support from your body, so your blood volume has increased. At week 8, your heart is pumping 50 percent more blood per minute than before you conceived.

You may begin or continue to experience symptoms such as:

  • nausea and vomiting, or “morning sickness
  • moodiness
  • weight gain or loss
  • bloating, gas, and constipation
  • increased sense of smell
  • sensitivity to those intense smells
  • excess saliva
  • food aversions and cravings
  • indigestion and heartburn
  • need to urinate more frequently
  • fatigue
  • increase in vaginal discharge
  • mild pelvic cramping
  • occasional vaginal spotting
  • breast changes such as enlargement, tenderness, tingling, nipple erection, nipple sensitivity, darkening areola
  • areolar bumps, which are actually sweat glands, known as Montgomery tubercles

Vaginal discharge

This thin, milky vaginal discharge, called leucorrhea, is a good sign. Your body is taking instinctual steps in protecting your birth canal from infection and protecting its natural bacterial environment.

The vagina needs a harmonious balance of good and bad bacteria to remain healthy and free of infection.

If you are concerned about a discharge or any other symptom, ask your health provider about it.

Hormonal changes mean that there is increased blood flow through your body.

This is necessary to enable the baby to grow, but if blood collects in weaker parts of the blood vessels, it can lead to bulges known as varicose veins.

Varicose veins can appear:

  • in the legs
  • around the rectum, where they are known as hemorrhoids or piles
  • around the genital area

Varicose veins sometimes cause discomfort. The legs may ache and feel heavy, and the skin around the vein may feel itchy or as if it is throbbing or burning.

To reduce the risk and impact of varicose veins, try to:

  • avoid standing still all day, if possible
  • avoid crossing your legs when sitting
  • put your feet up above the level of your heart whenever possible
  • get regular, moderate exercise, for example, walking
  • maintain a healthy weight
