8 Weeks Pregnant: Your Symptoms

At 8 weeks pregnant, your baby is approximately the size of a kidney bean and is developing rapidly — tiny fingers and toes are forming, and the facial features are becoming more distinct. For many women, week 8 is around the time their booking appointment is arranged or takes place. This is your first formal midwife appointment, where your medical history is taken, blood tests are arranged, and your pregnancy care plan is discussed. It is a good milestone to aim for if you haven't yet made contact with your GP or maternity team.

Hormonally, week 8 is often one of the more intense weeks of the first trimester. hCG levels are near their peak, which is why symptoms like nausea and fatigue can feel particularly strong right now. For most women, this week sits close to the height of first trimester discomfort — and knowing that things typically improve from around weeks 12 to 14 can make it easier to get through.

Common Symptoms at 8 Weeks

• Nausea and morning sickness — Often at or near its worst around weeks 8 to 10, pregnancy nausea is driven by high hCG levels. It can range from a constant background queasiness to frequent vomiting. Eating little and often, staying hydrated, and avoiding strong smells can all help.
• Fatigue and tiredness — Profound exhaustion is one of the most commonly reported symptoms at 8 weeks. Your body is working hard to grow a placenta, increase blood volume, and support your baby's development. Rest is not optional — it is necessary.
• Breast tenderness and growth — Your breasts may feel noticeably larger, heavier, and sore to the touch. The nipples and areolae often darken, and small bumps (Montgomery's tubercles) may appear around the areolae — these are normal glands preparing for breastfeeding.
• Bloating and constipation — Progesterone continues to slow your digestive system, which can cause constipation, trapped wind, and a bloated sensation. Drinking plenty of water and eating fibre-rich foods can ease this.
• Heartburn — The same muscle-relaxing effect of progesterone that slows digestion also relaxes the valve between your stomach and oesophagus, allowing stomach acid to rise. Eating smaller meals and avoiding lying down immediately after eating may help.
• Frequent urination — Still very common at 8 weeks. Your kidneys are filtering more blood, and the growing uterus begins to exert more pressure on the bladder.
• Mood swings — Hormonal fluctuations continue to affect your emotional state. Many women at 8 weeks also experience heightened anxiety — particularly around their first scan, which is still some weeks away at this point.
• Food cravings or aversions — Strong aversions to previously enjoyed foods, and sometimes unusual cravings, are typical at this stage. If aversions are making it hard to eat a balanced diet, focus on what you can tolerate and speak to your midwife at your booking appointment.
• Heightened sense of smell — Hyperosmia often peaks alongside nausea in the first trimester and can make certain environments or smells feel overwhelming. This usually settles as hCG levels begin to plateau.
• Slight weight changes — Some women begin to notice a small amount of weight gain, though for many this is mostly due to bloating rather than visible bump growth. Others may lose a small amount of weight if nausea is affecting their appetite — this is common and usually not a concern.
• Mild cramping or stretching sensations — As the uterus grows, some women feel occasional mild cramps or pulling sensations. These are usually harmless but always worth mentioning if they feel persistent or severe.
• Vivid dreams and disrupted sleep — Many women report unusually vivid or strange dreams from early in pregnancy. This is thought to be linked to hormonal changes and lighter sleep patterns, and is entirely harmless.

What's Normal at 8 Weeks

Equally, feeling very unwell at 8 weeks is also normal. Nausea and fatigue that peak around weeks 8 to 10 are a recognised pattern, and for most women this represents the hardest stretch of the first trimester before things begin to ease.

Symptoms can shift from day to day. A day where you feel more like yourself is not a sign that something has gone wrong. Hormone levels fluctuate naturally, and not every day will feel identical.

At 8 weeks, your uterus is approximately the size of a large orange. You are unlikely to have a noticeable bump yet, and most of the visible changes to your body at this stage — such as bloating and breast growth — are driven by hormones rather than baby size.

Practical Tips for Managing Symptoms at 8 Weeks

• For severe nausea: cold or room-temperature foods are often more tolerable than hot meals; strong smells in kitchens or public transport can be managed by breathing through your mouth or carrying something with a neutral or slightly pleasant scent.
• For constipation: increase fluid intake, eat foods high in fibre (such as oats, fruit, vegetables, and wholegrain bread), and try gentle movement like walking. Speak to your GP if constipation is severe — some laxatives are considered safe in pregnancy.
• For heartburn: smaller and more frequent meals tend to help; propping up the head of your bed slightly can reduce overnight symptoms. Your GP or midwife can advise on safe antacids if needed.
• For fatigue: accept help when offered, reduce non-essential commitments where possible, and try to go to bed earlier rather than pushing through the evening.

When to Seek Help

• Heavy bleeding (soaking a pad)
• Severe abdominal pain, particularly if it is one-sided — one-sided pain with bleeding can be a sign of an ectopic pregnancy and requires urgent assessment
• Fever above 38°C
• Inability to keep fluids down for 24 hours or more — this may indicate hyperemesis gravidarum, a condition that requires medical treatment
• Sudden, complete loss of all pregnancy symptoms — especially after previously seeing a heartbeat on a scan
• Pain or burning when urinating — urinary tract infections are more common in pregnancy and can cause complications if untreated; contact your GP or call 111

If at any point you are experiencing one-sided pain, shoulder-tip pain, or feel faint alongside any bleeding, seek emergency care immediately — call 999 or go to A&E.

Frequently Asked Questions

Yes. While many women feel their symptoms peaking around week 8, others experience relatively little. A symptom-free or symptom-light pregnancy is not inherently concerning. If you have had a scan confirming a heartbeat and your pregnancy is progressing, the absence of strong symptoms on their own is not a reason to worry. If you are anxious, speak to your midwife — they can offer reassurance and discuss whether an early scan would help.

When will my symptoms ease?

Most women find nausea and fatigue begin to lift between weeks 12 and 14, as hCG levels start to plateau and the placenta takes over hormone production. For some women this happens earlier; for a smaller number, nausea continues into the second trimester. If your symptoms are severe — particularly if you cannot keep food or fluids down — speak to your GP. Hyperemesis gravidarum is a medical condition and there are effective, safe treatments available.

Should I be worried about cramping at 8 weeks?

Mild, period-like cramping or occasional stretching sensations are common at 8 weeks as your uterus grows. They are usually nothing to be concerned about. However, cramping that is severe, persistent, or accompanied by heavy bleeding should always be assessed. Contact your midwife, call 111, or go to your nearest Early Pregnancy Unit (EPU) if you are worried.
