The first thirteen weeks of pregnancy is the First Trimester. Once fertilization has occurred and the embryo has been implanted in the wall of the uterus, the cells multiply rapidly as baby begins to form. Around the sixth week, the heart starts beating and it can be seen and heard on a scan. The head, neck, spine, genitals, and other organs also begin to form.
Your body releases high amounts of hormones for all this to happen, and these hormones can cause some dramatic changes.
You may experience nausea and bouts of vomiting (‘morning sickness’), you may be unable to stand strong smells, or have heartburn, and cravings or a strong dislike for certain foods. You may feel persistently tired, sleepy, and sometimes dizzy. Other possible symptoms are painful breasts and frequent urination.
You will need an ultrasound scan to determine that baby is growing well, the age of the baby, your expected delivery date, and to monitor the length of the cervix. Once the heart starts beating, you can hear it from the ultrasound scanner. Also, you will be placed on multivitamin supplements – particularly Folic acid, which is a very important nutrient at this stage of baby’s development.
Whatever symptom you might have can be addressed with medications. Rarely, you might need to be admitted for a while, especially if the vomiting is quite severe and you are not able to keep anything down. If there are no other issues, you will need an antenatal visit every four weeks.
