If you are soon to become a new parent, learning the stages of pregnancy can help you understand the development of your baby. Understanding pregnancy stages can also assist you with questions regarding nutrition, exercise and any prenatal tests that might need done. If you have any questions about pregnancy stages, be sure to speak with your doctor.
First Trimester
The first stage, also known as the first trimester, lasts from week one to week 12. The female body will start to go through many changes, including fluctuating hormone levels, which can lead to fatigue, tender breasts, mood swings, headaches and upset stomach. As for your developing baby, MayoClinic.com explains that the first trimester is a time of rapid growth and development. Your baby's brain, spinal cord and other organs will begin to form. Your baby's heart will also begin to beat and fingers and toes begin to take shape. During this stage, you should start prenatal care with your health-care provider.
Second Trimester
The second trimester, weeks 13 through 28, will be the second stage of pregnancy. Most women find that nausea goes away; bodily changes include a growing abdomen, swelling fingers and breasts and various body aches. Your baby's development will yield the ability to kick, make facial expressions and hear. Organ development continues in the baby; soon the brain and lungs will form. Continue with doctor visits to keep tabs on your health and your baby's as the pregnancy progresses.
Third Trimester
Many women find breathing difficult and notice they have to go to the bathroom more often in this third stage. Discomfort including back aches, swelling, and trouble sleeping may occur as the mother gets closer to labor. The baby will open its eyes during this stage and grow rapidly. The American Pregnancy Association notes that at 38 weeks, the fetus is considered full-term and should be ready to make its appearance at any time. Continue to monitor the baby's growth and any abnormal changes to prevent premature labor.
Labor and Delivery
The last stage is considered labor and birth. As you near your due date, your cervix becomes thinner and softer in a process called effacing. Signs that you are entering labor also include the membrane breaking, contractions starting and possibly an increase in energy as you prepare for childbirth. The birthing process is different for each woman and should always be monitored by your doctor. Ideally, the baby should be fully developed and delivered either vaginally or through a Cesarean procedure.
