What is Happening Inside Your Body?

You may begin feeling some pregnancy symptoms this week. Your body is producing copious amounts of pregnancy hormones. These hormones will have a widespread effect on your entire body.

Week5Web200Hormones will begin stimulating your breasts to produce breast milk. This can lead to breast tenderness. They will widen your blood vessels, drawing more of your blood toward your growing baby. This can lead to dizziness as your body draws blood away from your head and toward your pelvis.

Hormones will slow down your digestion, influence your brain chemistry, sharpen your sense of smell, and loosen your ligaments in your body to help make room for your baby to grow. You may feel digestive disturbances and nausea. You may experience mood swings or feel emotionally sensitive as hormones make changes in your brain and body.

You may start to feel fatigued or need to urinate more frequently, and you may feel some discomfort in your back or body as your ligaments begin to loosen. All this is normal and a sign that your body is doing its important job to nourish and care for your baby to be.

Your body has not begun to expand yet, and there are no big changes in your outward appearance.

How Big is Your Baby?

Your baby is about 2 millimeters long. It has now been 3 weeks since conception.
