We will discover everything about pregnancy stages in detail through this digital report from Bekoka press.

A normal pregnancy lasts 40 weeks, beginning with the first day of your last menstruation cycle (LMP) and ending with the baby’s birth. It is divided into three trimesters: the first, second, and 3rd trimesters. All through development, the fetus undergoes numerous shifts.

The first trimester (week 1–week 12)

In the first trimester, your body goes through a lot of adjustments. Hormonal fluctuations affect virtually every organ system in the human body. These changes may lead to signs even in the early stages of pregnancy. Your missed period is a clear indication that you are pregnant. Other modifications could include the following:

  • Extreme exhaustion
  • Breasts are tender and swollen. 
  • Your nipples may also be visible.
  • Uncomfortable stomach, with or without vomiting
  • Cravings or aversion to certain foods
  • Moves in mood
  • Constipation (trouble having bowel movements) (trouble having bowel movements)
  • Urine should be passed more frequently.
  • Headache
  • Heartburn
  • Gain or loss of weight

As your body changes, you may need to adjust your usual schedule, like going to bed earlier or eating small, regular meals.

Trimester two (week 13–week 28)

The 2nd trimester of pregnancy is usually easier with most women than the first. However, it is equally crucial to keep knowledgeable about your pregnancy during these months.

You may realize that signs such as nausea and tiredness are subsiding. However, other, more obvious differences in your body are now taking place. As the baby develops, your abdomen would then expand. But before the end of this trimester, you’ll notice your baby starting to move!

You could experience the following symptoms as your body adjusts to accommodate your growing baby:

  • Aches and pains in the back, abdomen, groin, or thighs
  • Skin discoloration around your nipples.

Trimester three (week 29–week 40)

You’ve reached the final stretch! Some of the same inconveniences you experienced in your second trimester would return. Furthermore, many women experience breathing difficulties and notice needing to use the restroom more frequently. This is because your baby is growing and putting more strain on your organs. Don’t worry; your baby is fine, and all these issues will go away once you have given birth.

You may notice the following new shape changes during the third trimester:

  • Breathing difficulty
  • Heartburn
  • Swelling of the ankles, fingers, and face. (Contact your physician right away if you notice any rapid or excessive swelling or if you obtain a significant amount of weight very quickly.)
