Pregnancy Stages – All Pregnancy Trimesters
Pregnancy consists of approximately 40 weeks, counting from the first day of your last menstrual period. The weeks divided into three Trimesters. Discover what happens with you and with the baby in these three stages In this article of PregnancyLead.
First trimester (from week 1 to 12) – All Pregnancy Trimesters
During the first trimester, the body goes through many changes. Hormonal changes affect virtually all organ systems. These changes can manifest symptoms even in the first weeks of pregnancy. Menstrual delay is a visible sign of fertility. Other modifications may include:

- Need to urinate more often
- Weight gain or loss
As the body changes, you probably need to make changes in your daily routine; For example, go to bed earlier or eat more frequently but in small amounts. Fortunately, most of these discomforts will disappear with time. And some women do not feel anything at all. If you have been pregnant before, you may feel different this time. All women are different; The same thing happens with pregnancies.
Second Trimester(from week 13 to 28) – All Pregnancy Trimesters
Most women feel that the second trimester of pregnancy is more accessible to carry than the first trimester. In any case, it is just as important to stay informed about pregnancy during these months.
You will notice that some symptoms, such as nausea and fatigue, will disappear. But now there will be new changes in the body that will be more evident. The abdomen will expand according to the growth of the baby. And before the end of this trimester, you will feel the baby begin to move.
As your body changes to make room for the baby, you are likely to have:
- Stretch marks in the abdomen, breasts, thighs or buttocks
- Darkening of the areolas
- A line on the skin that extends from the navel to the pubic hair

- Numbness or tingling in the hands called carpal tunnel syndrome

Third Trimester (from week 29 to 40) – All Pregnancy Trimesters
You’re in the final stretch! Some of the discomforts of the second quarter will continue. Also, many women feel short of breath and need to go to the bathroom more often. Because the baby is growing more and more and exerts more pressure on the organs. Do not worry, the baby is beautiful, and these problems will be relieved once you give birth.
Among the body changes that you will notice in the third quarter include:
