Pregnancy is a remarkable journey filled with physical, emotional, and hormonal changes that unfold week by week. While every pregnancy is unique, understanding what typically happens during each stage can help you feel more prepared, confident, and connected to your changing body. From the earliest signs of conception to the final weeks before birth, your body works continuously to support your growing baby.
This week-by-week guide walks you through the key physical changes you may experience during pregnancy, helping you know what’s normal, what to expect, and when extra care and monitoring become important.
Weeks 1–4: The Beginning of Pregnancy
Although you may not realize you’re pregnant yet, your body is already hard at work. Hormonal changes begin immediately after conception, preparing your uterus to support pregnancy. During this time, you may notice mild cramping, spotting, fatigue, or breast tenderness.
Hormones like progesterone and human chorionic gonadotropin (hCG) start increasing, which can cause early symptoms such as nausea or heightened sensitivity to smells. Emotionally, you might feel unusually tired or moody without knowing why.
Weeks 5–8: Early Symptoms Become Noticeable
This is when many women confirm their pregnancy. Morning sickness, which can occur at any time of the day, often begins during this phase. You may also experience frequent urination, bloating, food aversions, and extreme fatigue.
Your body is producing more blood to support the developing placenta, which can cause dizziness or shortness of breath. These changes are normal as your system adapts to pregnancy.
Weeks 9–12: The First Trimester Milestone
As you approach the end of the first trimester, your uterus begins to expand, though it may not yet be visible externally. Hormonal fluctuations can lead to mood swings, headaches, and constipation.
This is also a crucial period for prenatal screening. Tests such as the NIPT Test in Chandigarh help assess the risk of certain genetic conditions early in pregnancy, offering reassurance and supporting informed decision-making during this important stage.
Weeks 13–16: Entering the Second Trimester
For many women, the second trimester brings relief from nausea and fatigue. Energy levels often improve, and appetite returns. Your growing uterus may cause a small baby bump to become visible.
You may notice changes in your skin, such as a pregnancy glow or darkening around the nipples. Mild back pain or stretching sensations in the lower abdomen are common as ligaments adjust to support your expanding uterus.
Weeks 17–20: Feeling Baby Movements
This stage is particularly exciting, as many women feel their baby’s first movements, often described as flutters or gentle kicks. Your weight gain becomes more noticeable, and your center of gravity shifts, which may affect posture and balance.
Anatomy scans performed during this period help assess your baby’s development. These ultrasounds provide valuable insight into fetal growth and organ formation, giving you a clearer picture of your pregnancy progress.
Weeks 21–24: Visible Changes and Growing Comfort
Your belly continues to grow, and you may start experiencing stretch marks as your skin adapts. Increased blood flow can cause swelling in your feet or ankles, especially after long periods of standing.
Hormonal changes may also affect your gums, leading to sensitivity or mild bleeding. Staying hydrated, maintaining good posture, and wearing supportive footwear can help ease physical discomfort during this phase.
Weeks 25–28: Preparing for the Third Trimester
As you near the third trimester, your baby’s movements become stronger and more regular. You may experience heartburn, indigestion, or shortness of breath as your uterus presses against your stomach and diaphragm.
This is also a common time for glucose screening and detailed imaging. The NT Scan in Chandigarh is often discussed during pregnancy care planning, as it plays a key role in assessing fetal development and supporting early health insights.
Weeks 29–32: Increased Body Awareness
Your body now carries additional weight, which may cause back pain, leg cramps, or pelvic pressure. Sleep can become more challenging due to frequent bathroom trips and difficulty finding a comfortable position.
You might notice Braxton Hicks contractions—irregular tightening of the uterus that prepares your body for labor. These are typically painless and different from true labor contractions.
Weeks 33–36: Baby Drops Lower
During this stage, your baby may move into a head-down position, causing a sensation known as “lightening.” This can relieve pressure on your lungs but increase pressure on your bladder.
Fatigue may return as your body prepares for childbirth. Swelling in hands and feet is common, and maintaining gentle activity along with proper rest can help manage discomfort.
Weeks 37–40: The Final Stretch
Your body is now preparing for labor. The cervix may begin to soften and dilate, and you could experience increased pelvic pressure, back aches, or nesting instincts.
While excitement builds, it’s also normal to feel anxious or impatient. Staying connected with your healthcare provider and monitoring changes closely helps ensure both you and your baby are ready for delivery.
Emotional Changes Throughout Pregnancy
Pregnancy affects not only your body but also your emotions. Hormonal shifts, physical discomfort, and anticipation of parenthood can bring a mix of excitement, worry, and sensitivity.
Open communication, emotional support, and proper prenatal care play a vital role in maintaining mental well-being throughout pregnancy.
Final Thoughts: Embracing Each Week of Pregnancy
Understanding pregnancy week by week empowers you to embrace the changes happening in your body with confidence and awareness. While some symptoms may feel challenging, each stage brings you closer to meeting your baby.
By staying informed, attending regular check-ups, and listening to your body, you can navigate pregnancy with greater ease and reassurance. Every week tells a story of growth, strength, and transformation—one that is uniquely yours.
