Congratulations on reaching week 13 of this incredible journey with your partner!

Bobo will be sending you and your partner weekly updates on your pregnancy progress, child development, and Canadian based information up to the age of two. Here's

what you can expect during this stage of your pregnancy.

​​

Understanding Your Baby's Development

Around 13 weeks into the pregnancy, your little one is about the size of a lemon. At this stage, remarkable developments are underway. Your baby is now producing urine, and their bones are beginning to harden. Moreover, their vocal cords and intestines are currently in the process of development, setting the stage for future milestones.

​

Partner's Role in Healthcare Decisions: Screening Tests

As the pregnancy progresses, it's essential to be aware of various healthcare options, particularly concerning screening tests, to ensure the well-being of both the mother and the baby. Throughout pregnancy, several screening examinations are available to assess potential developmental concerns in the fetus.

• First Trimester Combined Screening: Typically conducted between 11 and 13 weeks. Comprising both the nuchal translucency ultrasound and a blood test, typically performed on the same day. It screens for chromosomal abnormalities.

• Integrated Prenatal Screening: Typically the first blood test and ultrasound conducted between 11 and 13 weeks, and the second blood test between 15 and 20 weeks. It mirrors the First Trimester Combined Screening followed by the Alpha-fetoprotein assay. It encompasses ultrasound, nuchal translucency measurement, and two blood tests to assess the risk of chromosomal abnormalities or neural tube defects.

Physical and Emotional Changes

​

During this stage of the pregnancy journey, your partner may notice that certain symptoms persist while others gradually ease. Symptoms such as changes in food preferences, heartburn, vaginal discharge, indigestion, constipation, visible veins due to increased blood flow, and faintness or dizziness might continue for her. Additionally, she might experience cramping, a return of appetite, or a stuffy nose due to increased blood volume or hormonal changes. Overall, her energy levels may start to improve, and she may begin to feel more comfortable as her body adapts to the changes of pregnancy.

​

Supporting Your Partner

As she progresses through her second trimester, you can assist her by ensuring she remains physically comfortable and emotionally supported. Additionally, be attentive to her needs and concerns, actively listening and providing reassurance whenever necessary. Engage in open communication about any changes or developments in the pregnancy, and collaborate on plans for the future, including parenting strategies and preparations for the baby's arrival.
