Second trimester is the second phase of pregnancy. It includes week 13 through 28. 

Second trimester of pregnancy brings a different set of body changes although the baby during this period continues in his growth and development process. Fortunately, the risk of miscarriage drops as nearly 80% of them occurs during the first trimester.

Towards the end of the second trimester, a woman starts feeling pregnancy aches as uterus keeps on growing and it can result in round ligament and back pain. Many women start feeling Braxton-Hicks contractions, after the 20th week of pregnancy, which are false contractions that prepare your body for true labor.

What to Eat During Second Trimester of Pregnancy

Eating a balanced diet of fresh fruits and green vegetables is vital for a mother and her baby in the second trimester. Actually, food that a mother eats is the only source of nutrients and nourishment for a baby. That is why eating healthy is important for pregnant women. You want to eat things that are going to promote development and growth in the baby. Healthy food includes the proper dose of minerals, vitamins, proteins, fats, carbohydrates and plenty of fresh liquids, and water. Calcium is especially vital for a baby as it helps in the development of teeth and bones in a baby. It is better to eat home-cooked meals as they are fresh and healthy.

  • Pumpkin seeds
  • Peanut butter
  • Dried fruits
  • Carrots
  • Cabbage
  • Beans
  • Broccoli
  • Avocado
  • Dairy products like milk, cheese and yoghurt

Second Trimester of Pregnancy Ultrasound

A doctor generally recommends an Ultrasound during 18th and 20th week of pregnancy. This scan helps in evaluating physical features and size of a baby. The sonographer measures the circumference of a baby’s head to determine proper development of the brain and skull.

During the first half of the second trimester, it is possible to see your baby’s skeleton through its skin as it is transparent. It is also possible to determine sex of a baby after 18th week as his reproductive organs are visible in ultrasound.
