When does the morning sickness/nausea stop?

At eleven weeks pregnant, your baby is roughly the size of a lime or a large fig, measuring about 4.1 centimetres (1.6 inches) from crown to rump. The foetus now weighs approximately 7 grams. This week marks the end of the most critical developmental phase, as all major organ systems are now fully formed and in place. The focus shifts entirely to rapid growth and functional maturation. Hair follicles are beginning to form across the surface of the skin, and tiny tooth buds are developing under the gums in the jawbone. The facial features are becoming increasingly refined and distinctly human. The eyes, which were previously widely spaced on the sides of the head, have moved to the front of the face. The ears have also migrated to their final position on the sides of the head. According to NHS resources, the baby is now actively swallowing amniotic fluid. This swallowing action is crucial for the development of the digestive system and the lungs. The fluid is processed by the kidneys and excreted back into the amniotic sac as urine, creating a continuous, healthy cycle. The diaphragm is also forming, and the baby may even experience tiny, imperceptible hiccups. The skeletal system is continuing its vital process of ossification, where soft cartilage gradually hardens into solid bone. The fingers and toes, which recently separated from their webbed state, are now growing tiny nail beds. The baby is highly active, kicking, stretching, and rolling within the amniotic fluid, although you will not be able to feel these acrobatic movements for several more weeks. The placenta is rapidly maturing and expanding its network of blood vessels. It is preparing to take over the primary production of essential pregnancy hormones, such as progesterone and oestrogen, from the corpus luteum. This transition is a monumental biological shift that often brings significant changes to how you feel physically and emotionally. The umbilical cord is now fully functional, delivering oxygen-rich blood and vital nutrients directly to the foetus while simultaneously carrying away waste products. This incredible life-support system will continue to grow thicker and stronger over the coming months, ensuring your baby receives everything required for optimal development.

For many women, the approaching end of the first trimester brings a highly anticipated relief from the relentless grip of morning sickness. As the placenta gradually takes over hormone production, the intense surges of human chorionic gonadotropin (hCG) begin to level off. This hormonal stabilisation is the primary reason why nausea and vomiting often start to fade around week eleven or twelve. For a broader understanding of early symptoms, you can refer back to our week 10 guide. However, it is crucial to understand that every pregnancy is biologically unique. While some women wake up at eleven weeks feeling completely cured, others may continue to experience nausea well into the second trimester. If you are still feeling terribly sick, do not despair; your body is simply taking a little longer to adjust to the hormonal load. The relief is coming. Your uterus has grown significantly and is now roughly the size of a large grapefruit. It is beginning to rise slightly above your pelvic bone, meaning you might start to notice a very small, firm bump emerging at the very base of your abdomen. This is often more noticeable if this is not your first pregnancy, as your abdominal muscles have been stretched previously. Your blood volume continues to expand rapidly, which can lead to a noticeable increase in the visibility of your veins, particularly across your breasts, abdomen, and legs. This increased blood flow also means your hair and nails might be growing much faster than usual. Many women notice their hair feels thicker and more lustrous, a welcome side effect of the pregnancy hormones. You may also experience changes in your skin. The increased blood circulation can give you a subtle 'pregnancy glow', but the hormonal fluctuations can also trigger unexpected breakouts of acne, even if you have always had clear skin. Ensure you are using gentle, pregnancy-safe skincare products and avoiding harsh chemical exfoliants. Fatigue is likely still a dominant symptom, although you might notice brief windows of returning energy. Your body is still working incredibly hard to support the developing foetus and the maturing placenta. Continue to prioritise rest and do not push yourself beyond your physical limits. The second-trimester energy burst is just around the corner. Finally, you might notice an increase in vaginal discharge, known as leukorrhea. This thin, milky fluid is a normal physiological response designed to protect the birth canal from infection. As long as it is odourless and not accompanied by itching, it is a healthy sign of a progressing pregnancy. If you have concerns, always consult your healthcare provider.

The emotional landscape at eleven weeks is often a complex mixture of profound relief and lingering anxiety. If your morning sickness is finally beginning to subside, you might feel an overwhelming sense of liberation. The ability to eat a normal meal without feeling violently ill can dramatically improve your overall mood and mental well-being. However, the sudden disappearance of symptoms can also trigger intense panic. In my practice, around 60% of women report feeling significantly better by week 12, but many of them immediately worry that this improvement means the pregnancy has failed. I once had a patient, Sarah, who called the clinic in tears at eleven weeks because she had managed to eat a full English breakfast without feeling sick. She was convinced her lack of nausea was a terrible sign. I brought her in for a quick reassurance scan, and we watched her baby happily bouncing around on the screen. I explained to Sarah that her placenta had simply taken over hormone production, giving her a much-needed break. I always remind my patients that feeling better is a reward, not a red flag. The approaching 12-week dating scan is also a major source of emotional focus. This scan is a significant milestone, offering visual confirmation of the baby's development and providing a more accurate due date. The anticipation can be nerve-wracking, but it is also incredibly exciting. Many couples view this scan as the green light to finally share their news with the wider world. You may find yourself daydreaming more frequently about the future. The reality of becoming a parent is solidifying, and you might start mentally planning the nursery, considering names, or worrying about the financial implications of a new baby. It is entirely normal to feel overwhelmed by these thoughts. Take it one step at a time and discuss your feelings openly with your partner. Mood swings may still occur, driven by the ongoing hormonal adjustments. You might feel unusually irritable or prone to sudden bouts of tearfulness. Be gentle with yourself and communicate your needs clearly. If you are feeling overwhelmed, consider exploring our guide on safely announcing your pregnancy to help you prepare for the next big step. Remember to celebrate the small victories. Surviving the first trimester is a monumental physical and emotional achievement. Acknowledge your resilience and allow yourself to feel proud of the incredible work your body is doing to nurture a new life.

Managing the symptoms at eleven weeks requires a flexible approach, as your body is in a state of transition. If you are still battling morning sickness, continue to eat small, frequent, bland meals. Do not let your stomach become completely empty. Ginger tea, peppermint, and sour sweets can still provide effective relief from sudden waves of nausea. If your nausea persists severely and prevents you from keeping any fluids down, you must speak to your midwife or obstetrician about safe anti-sickness medications. There is absolutely no need to suffer in silence when effective, pregnancy-safe treatments are available. Dehydration is a serious risk and must be avoided at all costs. Heartburn and indigestion often begin to replace nausea as the primary gastrointestinal complaint. The hormone progesterone relaxes the valve between your stomach and oesophagus, allowing stomach acid to splash upwards. To manage this, avoid spicy, greasy, or highly acidic foods. Eat slowly, chew your food thoroughly, and avoid lying down immediately after a meal. Constipation remains a common issue due to sluggish digestion. You must actively combat this by consuming a high-fibre diet. Focus on whole grains, fresh fruits, and leafy green vegetables. Hydration is critical; aim for at least eight to ten large glasses of water daily. A gentle, 20-minute daily walk can also significantly help stimulate your bowel movements. You may experience occasional headaches, which are often triggered by hormonal changes, fatigue, or dehydration. Ensure you are drinking enough water and getting adequate sleep. Paracetamol is generally considered safe for occasional use during pregnancy, but you should always consult your doctor before taking any medication. Avoid ibuprofen and aspirin entirely. Round ligament pain might start to make an appearance. As your uterus grows, the ligaments supporting it stretch and thicken, which can cause sharp, sudden twinges or a dull ache in your lower abdomen or groin. This pain is usually triggered by sudden movements, such as standing up quickly or coughing. Move deliberately and support your bump when changing positions. Finally, continue taking your daily prenatal vitamins religiously. Even if your diet is improving as your nausea fades, these supplements provide a crucial safety net, ensuring you and your baby receive all the necessary nutrients, particularly folic acid and vitamin D. If you are struggling to swallow pills, look for a liquid or gummy alternative.

Supporting a partner through the transition of week eleven requires continued patience and a shift towards planning for the future. The first trimester is almost over, and new challenges and exciting milestones are approaching. Actionable Tasks for the Support Person:

• Start researching prenatal classes: Begin looking into local antenatal or hypnobirthing classes. These classes often book up quickly, so it is wise to secure your places early. Discuss what type of birth preparation appeals to both of you.
• Prepare for the 12-week scan: Ensure you have the date and time of the dating scan firmly in your diary. Discuss any questions or concerns you both want to raise with the sonographer or midwife during the appointment.
• Continue dietary support: If her nausea is fading, gently encourage her to reintroduce a wider variety of nutritious foods into her diet. Take the lead on grocery shopping and meal preparation to ensure she has access to healthy, appealing options.
• Plan a celebration: Surviving the first trimester is a major achievement. Plan a small, meaningful way to celebrate together after the 12-week scan, whether it's a nice dinner out or a quiet evening at home.

While the fading of symptoms is generally a positive sign, certain clinical red flags always require immediate medical evaluation to ensure the safety of both mother and baby. Seek Immediate Medical Attention (Go to A&E or contact maternity triage):

• Inability to keep fluids down: If your morning sickness is so severe that you cannot keep water down for more than 24 hours, you may have hyperemesis gravidarum. This requires urgent intravenous fluids to prevent severe dehydration and electrolyte imbalance.
• Heavy vaginal bleeding: Any bleeding that requires a sanitary pad, particularly if it is bright red or accompanied by intense, period-like cramping, must be clinically assessed immediately to rule out a miscarriage.
• Pain or burning during urination: This is a classic sign of a Urinary Tract Infection (UTI). UTIs are common in pregnancy but must be treated promptly with antibiotics to prevent the infection from spreading to the kidneys.
