Understanding the First Trimester January 24, 2022 by Dr. Lori Gore-Green (Edit)
The first trimester refers to the first 12 weeks of pregnancy. It’s an exciting time, but it’s also critical because it is when the baby develops all the major organs. During the first trimester, the baby’s brain and nervous system develop. The heart starts beating, and blood flows through the veins and arteries. The arms, legs, and backbone form, and the baby’s organs also start to develop, including the lungs, liver, and kidneys. Here is what to expect during that time. Fertilization of the egg – The first trimester is when the fertilization of the ovum occurs. The sperm has to reach and penetrate an egg for this to happen. If it doesn’t, pregnancy will not occur. Implantation – Once conception happens, the zygote attaches itself to the mother’s uterus lining through implantation, which usually occurs about a week after fertilization. Hormonal changes – The body’s hormone levels go up in this trimester during the first few weeks. This will cause the pregnant to feel nauseous and tired during this time because her body is working hard to support the baby. drlorigore-green.com/understanding-the-first-trimester/
