The second trimester of pregnancy (weeks 13 to 27) is often considered the most enjoyable phase. Nausea usually starts to settle, your energy may return, and you might feel a little more like yourself. But as your body changes to support your growing baby, you’ll also notice new symptoms, some welcome, others a bit unexpected.
Here’s what’s normal in the second trimester, what’s worth checking, and how to stay comfortable as your pregnancy progresses.
What’s Happening to Your Body?
During the second trimester, your baby is growing rapidly. Your uterus expands, hormones shift, and your blood volume increases. These changes can bring a whole range of symptoms, most of them completely normal.
Common Second Trimester Symptoms
1. A Growing Bump
This is often the trimester where your pregnancy becomes visible to others. Your uterus is moving upwards, and your baby is getting bigger by the week. Expect to gain around 1 to 2 pounds a week (depending on your pre-pregnancy weight).
2. Breast Changes
Breasts may continue to grow and feel tender or heavy. You might notice darkening of the areolas, more visible veins, or even colostrum (early milk) leaking. Wearing a supportive maternity or nursing bra can help reduce discomfort while our Hot & Cold Breast Therapy Pads can help ease any pain you may feel during this time.
3. Round Ligament Pain
As your uterus stretches, the ligaments supporting it can cause sharp or achy pains in your lower belly or groin. This is common but should ease with rest and gentle movement. If it doesn’t, then it is advised you speak with your midwife.
4. Nasal Congestion and Nosebleeds
Increased blood flow and hormone levels can cause swelling in the nasal passages, leading to a stuffy nose or nosebleeds.
5. Skin Changes
Many people notice new skin changes such as:
- Linea nigra (a dark line running down your belly)
- Stretch marks on your tummy, breasts, or thighs
- Acne or pigmentation patches (melasma)
Using SPF daily can help manage skin sensitivity, and moisturiser may ease dryness or itching.
6. Increased Appetite
With morning sickness easing, your appetite may return. Try to eat balanced meals and snacks throughout the day to support your baby’s growth.
7. Vaginal Discharge
A clear or white discharge (leukorrhoea) is normal. It helps keep the vagina clean and prevent infection. If it changes colour, smells unpleasant, or is itchy, speak to your midwife.
8. Constipation
Hormones slow digestion, and the growing uterus puts pressure on your bowel. Drink plenty of water, eat fibre-rich foods, and stay active.
9. Leg Cramps
Often striking at night, leg cramps can be managed with stretching, hydration, and gentle exercise. It can be caused when your potassium levels are slightly low, so eating a banana a day or drinking some coconut water can also help. A magnesium body moisturiser like our Calming Bedtime Butter can help soothe restless legs.
10. Baby Movements
You may start feeling your baby move between 16 and 24 weeks. This can feel like flutters, bubbles, or light tapping - a magical moment of connection.
When to Call Your Midwife
Most second trimester symptoms are completely normal. But get in touch with your midwife or GP if you experience:
- Severe abdominal pain
- Heavy bleeding or unusual discharge
- Persistent headaches or blurred vision
- Sudden swelling in your hands, face, or feet
- Changes in baby’s movements after 24 weeks or absent movements by 24 weeks
