Week 7 Pregnancy
You are 7 weeks pregnant and in your first trimester. Your baby is about the size of a blueberry. This week's key development: Budding Arms & Legs. NHS note: Ensure you've registered with a midwife.
Baby's Development
Your baby is about the size of a blueberry.
Budding Arms & Legs — Arm and leg buds are growing longer, and tiny paddles that will become hands are forming. The brain is developing at a staggering pace — around 100 new brain cells every minute. Nausea may be peaking this week.
Your Symptoms
- Excessive saliva
- Food cravings
- Acne or skin changes
- Mood swings
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
Ensure you've registered with a midwife. You'll receive a 'Bounty' pack or similar resources soon.
Practical Advice for Week 7
Nutrition
- Folic acid and vitamin D — keep going.
- If food aversions are strong, eat whatever you can manage without guilt.
- Zinc-rich foods (meat, shellfish, seeds) support your baby's cell growth.
- Avoid shark, swordfish, and marlin due to mercury content.
Exercise
- Modify exercises if you're feeling nauseated — shorter, gentler sessions are fine.
- Walking in fresh air can actually help reduce nausea.
- Gentle Pilates strengthens your core without strain.
- Stay hydrated before, during, and after any exercise.
Wellbeing
- Excessive saliva (ptyalism) is a real and annoying symptom — it does get better.
- Mood swings are driven by hormones and are completely normal.
- If you're struggling with food cravings, indulge sensibly but don't restrict yourself.
- Try keeping a gratitude journal — it can genuinely shift your mindset during difficult days.
Preparation
- Ensure you're registered with a midwife and have a booking appointment date.
- Think about whether you want NHS or private midwifery care (or a combination).
- Start a pregnancy folder — keep appointment letters, scan photos, and your maternity notes together.
- Research antenatal classes in your area — NHS classes are free but book up quickly.
