This week marks the start of your second trimester, and you may be feeling better as many of the initial symptoms of pregnancy have subsided. You are likely to have gained a few pounds by now, and your uterus is growing bigger every day. 

The foetus at week 13 is about the size of a peach. By this stage in your pregnancy, your baby’s bones are starting to harden and he or she is starting to move around a lot inside the womb. His or her ovaries or testes are now fully developed inside. 

Pregnancy can be an exciting time filled with anticipation, joy and sometimes even a little bit of anxiety. Whether this is your first baby or your fifth, each pregnancy is unique and special. 

Many women find that they start to feel better around week 13 of their pregnancy. The initial symptoms of nausea and fatigue may have subsided, and many women start to feel more energetic. However, it is important to take things easy and listen to your body as you continue with your pregnancy. Some women still experience symptoms from earlier weeks in their pregnancy for some time yet, including: 

  • Nausea (sometimes known as ‘morning sickness’) 
  • Food aversions 
  • Food cravings 
  • Increased sense of smell 
  • Mood swings 

As you progress into your second trimester of pregnancy your symptoms could change. Here are some common ones to look out for: 

  • Sore breasts 
  • Leg cramps 
  • Swollen and/or bleeding gums 
  • Constipation 
  • Bloating 
  • Round ligament pain 

The mother’s body is going through many changes at 13 weeks pregnant. The foetus is growing larger, and the uterus is expanding to make room for the baby. The mother’s breasts are also changing to prepare for breastfeeding. The mother’s body is also preparing for labour, and the muscles and ligaments in the pelvic area are loosening in preparation. 

That’s all for this week, be sure to check back next week!
