Stages of pregnancy

The first day of your last menstrual period marks the start of your pregnancy, which lasts about 40 weeks. Three trimesters are used to organize the weeks. Learn what occurs to you and your baby during each of these stages.

First trimester (week 1 to 12)

The body undergoes numerous changes during the first trimester. Hormonal changes have an impact on almost every organ system. Even in the first few weeks of pregnancy, these changes might cause symptoms. A late menstrual period is a sure sign that you're pregnant. Other modifications could include:

  • Exhaustion
  • Breasts that are tender and swollen. It's also possible that your nipples will get lumpy.
  • Vomiting (morning sickness) is a possibility if your stomach is upset.
  • Food preferences (desires) or dislikes (aversions)
  • Swings in mood
  • Constipation is a common complaint among people (difficulty passing stools)
  • Urinate more frequently
  • Headache
  • Heartburn
  • Gaining or losing weight.
Second trimester (week 13 to 28)

The majority of women believe the second trimester of pregnancy is less difficult than the first. However, it's just as important to stay informed about your pregnancy during these months.

You'll notice that some symptoms, including nausea and exhaustion, will go away. However, new alterations in the body will be more visible now. As your baby grows, your abdomen will enlarge. You'll start to feel the baby move before the conclusion of this trimester.

Third trimester (week 29 to 40)

Some second trimester discomforts will persist. Furthermore, many women report shortness of breath and require more frequent restroom visits. This is due to the baby's increasing size, which puts extra pressure on the organs. Don't worry, the baby is fine, and these issues will go away once you deliver.

Your cervix becomes thinner and softer as you move closer to your due date (this process is called effacement). This is a natural procedure that aids in the opening of the birth canal (vagina) during labor. As your due date approaches, your health care practitioner will do a vaginal exam to check on your development.
