Week 6 Pregnancy
You are 6 weeks pregnant and in your first trimester. Your baby is about the size of a lentil. This week's key development: A Flickering Heartbeat. NHS note: Routine care continues.
Baby's Development
Your baby is about the size of a lentil.
A Flickering Heartbeat — At an early scan this week, you might see and hear your baby's heartbeat for the very first time. Tiny arm and leg buds are forming, and facial features are beginning their delicate development. Fatigue may feel overwhelming — your body is building a placenta from scratch.
Your Symptoms
- Nausea
- Sore breasts
- Bloating
- Frequent trips to the toilet
Every pregnancy is different. You may experience all, some, or none of these symptoms — and that's completely normal. If anything concerns you, speak to your midwife.
NHS Appointments
Routine care continues. If you have any bleeding or severe pain, contact your local Early Pregnancy Unit (EPU).
Practical Advice for Week 6
Nutrition
- Continue folic acid and vitamin D.
- Stay hydrated — dehydration can worsen nausea and headaches.
- Eat little and often rather than three large meals.
- Include vitamin C-rich foods (oranges, peppers, strawberries) to help absorb iron.
Exercise
- Swimming is excellent — the water supports your body and feels wonderful.
- Continue pelvic floor exercises — aim for 3 sets of 10 squeezes per day.
- Avoid lying flat on your back for extended periods during exercise.
- Prenatal yoga classes are a great way to stay flexible and meet other expecting parents.
Wellbeing
- Your body is building an entire organ (the placenta) — the tiredness is real and justified.
- If you have severe nausea or vomiting, speak to your GP — hyperemesis gravidarum is treatable.
- Keep communication open with your partner — pregnancy affects both of you.
- A warm (not hot) bath before bed can help with sleep.
Preparation
- If you have any bleeding or severe pain, contact your local Early Pregnancy Unit (EPU).
- Check whether your employer has an occupational health team for pregnancy support.
- Start reading about the different types of birth options available in the UK.
- Think about whether you want combined screening at your dating scan (weeks 11–14).
Tip of the Week
