Pregnancy is a unique experience for every individual. While some early pregnancy symptoms can be unmistakable, others might be subtle or even go unnoticed. It's completely normal to experience a mix of physical, emotional, and hormonal changes – or sometimes very few at all.
Understanding the early signs of pregnancy, what to expect from your growing bump, and how your body is changing week by week can help you feel more in tune with your pregnancy journey. Here's your guide to early pregnancy symptoms, when baby bumps typically start to show, and what these changes mean for you and your baby.
What Are the Early Signs of Pregnancy?
You might notice changes in your body even before a missed period. Early signs of pregnancy can vary widely, but the most common symptoms include:
- A missed or lighter period (especially if your cycle is usually regular)
- Morning sickness or nausea (which can strike at any time of day)
- Extreme fatigue or low energy
- Increased urination due to hormonal shifts
- Heightened sense of smell and food aversions
- Tender or swollen breasts
- Unusual cravings or taste changes
Some people may also notice mild cramping or bloating, mood swings, or light spotting (known as implantation bleeding). These symptoms are all linked to the early hormonal changes that support your pregnancy, particularly increased levels of progesterone and hCG (human chorionic gonadotropin).
When Does a Baby Bump Start to Show?
Your baby bump usually starts to become visible during the second trimester, typically between weeks 13 and 16. However, some people may show earlier or later depending on:
- Whether it’s your first pregnancy
- Your body shape and muscle tone
- How many babies you’re carrying
By week 20, most pregnant people will have a noticeable bump as the uterus reaches up to the level of the belly button. It’s important to remember that every bump is different. Don’t compare your pregnancy to others - bump size and shape can vary greatly.
Early Signs Your Bump Is Starting to Show
Before your bump visibly pops, you might notice signs that your body is changing:
- Bloating or a feeling of fullness
- More frequent urination as your uterus starts pressing on the bladder
- Increased appetite or digestive changes
- Lower back ache
- Mild pelvic pressure or stretching sensations
Many people begin taking bump progress photos from the first trimester onwards as a way to document their pregnancy. This can be a fun and affirming way to observe subtle changes over time.
Emotional and Hormonal Changes
Hormonal fluctuations in early pregnancy can also affect your emotions. You might feel:
- More tearful or irritable
- Easily overwhelmed
- Anxious or excited
These are all normal responses to the big changes your body is going through. If you feel persistently low or anxious, speak to your midwife or GP.
What Is Fundal Height and Why Does It Matter?
As your pregnancy progresses, your midwife will measure something called fundal height – the distance from your pubic bone to the top of your uterus. It helps track your baby’s growth and development.
- Fundal height usually begins being measured from around week 24
- Measurements are compared to standard growth charts
- This check helps to assess whether baby is growing consistently
If there are concerns (baby measuring smaller or larger than expected), your midwife may arrange an additional scan to investigate further.
How Does the Uterus Change as Baby Grows?
- In early pregnancy, your uterus is still nestled low in your pelvis
- By week 12, it starts rising above the pubic bone
- By week 20, the top of your uterus reaches your belly button
- From then on, it continues to grow upwards, which is why your bump becomes more pronounced
Alongside your growing uterus, you’ll also be carrying the placenta, amniotic fluid, and increased blood volume – all of which contribute to your bump’s size and shape.
What Else Happens in the Second Trimester?
The second trimester is often described as the "honeymoon phase" of pregnancy. Many early symptoms ease, and energy levels may improve. At your 20-week scan, you’ll get a detailed look at your baby’s development and may be able to find out the sex of your baby (depending on NHS policy and baby’s position).
- Baby begins moving regularly (usually felt between 16 and 24 weeks)
- Skin changes and stretch marks may appear
- You may begin to feel more emotionally connected to your baby
Tips for Managing Bump-Related Changes
