Pregnancy: 13-16 Weeks

Changes Your Body Will Experience

As you enter the 2nd trimester of your pregnancy, the uterus begins to expand and shift upward. Physical changes and sensations are more pronounced and a woman's newly rounded shape announces her pregnancy to the rest of the world. An increased level of estrogen circulating in the body at this time may produce more body cells that may produce skin blemishes. Some women experience nosebleeds related to this increase in hormones. Other women may notice a temporary darkening of the skin in the form of a line that appears from the navel to the pubic area. This is referred to as the "linea nigra."

  • Constipation
  • Breast tenderness subsides

  • Slight whitish vaginal discharge called "leukorrhea" (This discharge should not cause itching or burning; if it does, call your doctor).

Emotional Changes You May Experience

The steady weight gain pregnant women experience can cause a confusing array of emotions. One moment you're up because your outer self matches your inner sensations. The next moment you're down because you can't squeeze into a favorite outfit. It's important to realize weight gain is a normal part of pregnancy. Exercise can help offset feelings of awkwardness about your new shape and promote strength. Remember to eat healthy foods and do not skip meals, it's important for you and your baby's sake. It's normal to feel some apprehension as a new life grows inside of you. Concerns that the baby may not be perfect are very normal and common. If you feel overwhelmed with fearful thoughts and misgivings, consult your doctor or childbirth educator.

Be Alert to Warning Signs

Call your doctor if you experience any of the following:
  • Cramping and/or low back pain or ache
  • Vaginal bleeding
  • Severe swelling of ankles, fingers or face
  • Visual changes - seeing 'spots' or 'floaters'
  • Excessive or sudden weight gain (more than 2-pounds/week)
  • Difficulty accepting the pregnancy
  • Disruptive marital conflict
  • Physical or emotional abuse
How Is My Baby Growing?

By the end of your 4th month the baby is 4 inches long. Its sucking and swallowing reflexes are developed. Fingers and toes are well developed too. It even begins to get tooth buds; however, it can not survive outside the mother's uterus.
