Understanding Pregnancy Trimesters

Pregnancy is split into three trimesters, each lasting between 12 and 14 weeks. Every stage comes with its own changes and challenges:
 

• First Trimester (Weeks 1–12)

• Second Trimester (Weeks 13–26)

• Third trimester (weeks 27–40)

Each trimester has it's is marked by hormonal shifts, physical developments, and different symptoms as the fetus grows.

Causes of Body Changes During Pregnancy

The main cause of body changes during pregnancy are the changes in hormones. Estrogen and progesterone levels rise fast after conception and continue to fluctuate throughout pregnancy. These hormones help in fetal growth, keep the uterine lining healthy, and prepare the body for delivery and breastfeeding. Increased blood volume, metabolic changes, and uterine growth result in noticeable changes in the body.
 

Symptoms and Changes by Trimester
 

First Trimester (Weeks 1–12)
The first signs of pregnancy may appear within a week or two of conception.

• Missed Periods: This is commonly the first indication of pregnancy.  

• Nausea and Vomiting: It is commonly known as morning sickness, but can happen at any time throughout the day.

• Exhaustion: There are too many changes in the body that consume a lot of energy, which often lead to a feeling of fatigue.  

• Breast Sensitivity: The breasts may become swollen or painful.  

• More Urination: The expanding uterus exerts pressure on the bladder, resulting in more frequent urination.  

• Psychological changes: Mood swings may happen due to changes in hormone levels.  

• Food Dislikes or Cravings: There may be a strong liking or dislike for certain foods and smells.

Second Trimester (Weeks 13–26)

It is often known as the "honeymoon phase" of pregnancy since it is generally more pleasant.

• Visible Baby Bump: As the baby grows, the uterus expands, resulting in noticeable weight gain.

• Reduced Nausea: Morning sickness typically goes away in this trimester.

• Increased Energy: Many women feel more energetic and less worn out.

• Skin Changes: Some women may get a black line on their belly (linea nigra) or face pigmentation (melasma).

• Stretch Marks: As the skin expands, stretch marks may occur on the stomach, thighs, or breasts.

• Pain on one or both sides of the lower abdomen caused by stretched ligaments.

• Quickening: Around week 18-20, first-time mothers may start to feel fetal movement.

Third Trimester (Weeks 27–40)

In the final trimester, the body begins preparing for labor and delivery.

• Back pain: It is caused due to the baby's weight and changes in posture.

• Shortness of breath: It is because, as the uterus expands, it presses against the diaphragm.

• Frequent urination: As the baby's head settles into the pelvis, pressure on the bladder increases, resulting in frequent urination.

• Swelling: Mild swelling can be noticed in the feet, hands, and ankles.

• Braxton Hicks Contractions: These are irregular, painless uterine contractions that help to prepare the muscles for delivery.

• Insomnia: Sleep is difficult due to discomfort and frequent bathroom trips.

• Leaky Breasts: Colostrum (first milk, commonly known as liquid gold) may begin to leak from the nipples.

• Increased Pelvic Pressure: As the baby approaches birth, it descends further into the pelvis, exerting pressure.
