Pregnancy Week 10
Pregnancy Week 10
What to expect on pregnancy week 10
Pregnancy Week 10 brings continued rapid development. The head becomes rounder, the elbows can bend, fingers and toes continue lengthening, and early movements may be visible during an ultrasound even though you cannot yet feel them.
Pregnancy Week 10 Overview
The baby now weighs roughly five grams and is the size of a plum (1.25 to 1.68 inches). The groundwork for the baby's body has been fully laid down. Looking on an ultrasound you can see the baby moving around a lot, though it is too small for the mother to really notice.
Your morning sickness and nausea will start to ease up slightly though you will continue to be moody. Your blood volume will increase by about 40 percent and as a result you may notice your veins more, especially around your stomach, breasts, and thighs.
Understanding Pregnancy Week 10
Pregnancy Week 10 places you close to the end of the first trimester. Development is continuing quickly, even though the developing baby remains very small.
Mayo Clinic highlights several important Week 10 changes: the head becomes rounder, elbows can bend, and fingers and toes become longer while losing more of their earlier webbed appearance.
Development of the eyelids and outer portions of the ears also continues.
The NHS notes that small jerky movements are occurring and can be visible on an ultrasound scan, although they are far too subtle for the pregnant person to feel at this stage.
Important Clarification About the Original Week 10 Guide
Your original Week 10 information has been preserved exactly as provided. A few claims benefit from additional current medical context.
Size and Weight Estimates Vary
The original guide describes a weight of roughly five grams and a length of 1.25 to 1.68 inches, comparing the developing baby with a plum.
Current NHS Week 10 guidance gives an approximate crown-to-rump length of 30 millimeters, or about 1.2 inches, and compares the developing baby with a small apricot.
Food comparisons are not standardized between pregnancy websites, so a plum, apricot or similar comparison should never be treated as a precise measurement.
Week 10 Is Still at the End of the Embryonic Period
Pregnancy terminology can be confusing because gestational weeks are counted from the last menstrual period rather than conception.
ACOG describes Week 11 of the gestational pregnancy timeline as the beginning of the fetal stage. Therefore, Week 10 is still at the end of the embryonic developmental period in this gestational framework.
Blood Volume Does Not Suddenly Increase 40 Percent in Week 10
The original guide states that blood volume will increase by about 40 percent during Week 10.
Blood volume does begin rising early in pregnancy, but the approximately 40 to 45 percent figure commonly cited by medical sources describes the overall increase across pregnancy, not an increase that suddenly occurs or is fully completed during Week 10.
How Big Is the Baby at Pregnancy Week 10?
The developing baby continues growing quickly during the first trimester.
The NHS Week 10 guide describes a length of approximately 30 millimeters from head to bottom, roughly the size of a small apricot.
Small differences in gestational dating can create noticeable differences in expected crown-to-rump length because growth is rapid during early pregnancy.
This is why online measurements should be treated as approximate educational references rather than exact targets.
Arms, Elbows, Fingers and Toes During Week 10
The arms and legs continue changing rapidly during Pregnancy Week 10.
According to Mayo Clinic, the elbows can now bend. Fingers and toes become longer and continue losing the webbed appearance seen during earlier stages.
These tiny limbs are still developing and should not be imagined as complete newborn hands, feet, arms or legs.
The developing elbow joints allow the arms to take on increasingly defined positions.
The fingers continue growing and becoming more separate from one another.
The developing toes lengthen as the feet become more defined.
The early skeletal framework continues developing before later hardening into bone.
Head, Face, Eyelids and Ears at Week 10
The head remains large in proportion to the rest of the developing body, but its shape becomes rounder during Week 10.
Development of the eyelids continues, while the external portions of the ears become progressively more defined.
The NHS notes that the face is becoming more recognizably proportioned. The mouth has a delicate upper lip, nostrils are present and the jaw continues developing.
Tiny early structures associated with the primary teeth are also developing within the jaw.
Baby Movement During Pregnancy Week 10
Movement is already occurring even though you cannot normally feel it.
The NHS describes small jerky movements at Pregnancy Week 10 that can be visible during an ultrasound scan.
These movements occur because muscles, joints and the nervous system are continuing to develop.
However, movement at this stage is extremely small compared with the kicks and turns that become noticeable much later in pregnancy.
Pregnancy Week 10 Development Timeline
The head and facial region continue becoming more defined.
Development of the arms and joints allows increasingly complex positions and movement.
The digits continue separating and losing more of their earlier webbed appearance.
Facial and external ear structures continue their gradual development.
Tiny spontaneous movements may be visible during an ultrasound.
Maternal Changes During Pregnancy Week 10
Pregnancy symptoms can still be strong at Week 10, although you are moving closer to the second trimester.
The NHS notes that nausea, extreme tiredness, mood swings, sore breasts, food changes, indigestion, heartburn, dizziness and bloating can still occur during Week 10.
Some people begin noticing that certain symptoms are gradually easing, while others continue experiencing significant morning sickness for several more weeks.
Your uterus is also expanding. NHS guidance compares it with the size of a large orange at this stage, although the developing baby itself is much smaller.
Does Morning Sickness Ease During Pregnancy Week 10?
Some people may notice that nausea begins becoming less intense around this part of pregnancy.
However, Week 10 should not be treated as a deadline when morning sickness must improve.
The NHS notes that by the second trimester many early-pregnancy symptoms gradually fade, but nausea is still listed as a common Week 10 symptom.
Pregnancy symptoms vary considerably from person to person.
Possible Pregnancy Week 10 Symptoms
Morning sickness may continue, although some people begin noticing gradual improvement.
Extreme tiredness can still occur as the first trimester continues.
Breasts may remain enlarged, sore or more sensitive than before pregnancy.
Hormonal changes, tiredness and physical symptoms may contribute to emotional ups and downs.
Progesterone affects the digestive system and may contribute to gas and bloating.
Pregnancy-related digestive changes can lead to indigestion or heartburn in some people.
Blood Volume Changes During Pregnancy
Pregnancy places increasing demands on the cardiovascular system. The body gradually produces more circulating blood to support both the pregnant person and the developing pregnancy.
Cleveland Clinic notes that blood volume begins increasing during the first weeks of pregnancy and continues rising, with many pregnant people ultimately experiencing an overall increase of approximately 40 to 45 percent.
That does not mean blood volume suddenly rises 40 percent during Pregnancy Week 10. The change develops gradually across pregnancy.
The heart also works harder as pregnancy progresses, and heart rate and cardiac output can increase.
Why Might Your Veins Become More Visible?
Some pregnant people notice veins becoming easier to see beneath the skin as pregnancy progresses.
Increasing blood flow and changes in circulation can make superficial veins more noticeable, particularly in areas such as the breasts.
Skin tone, body composition and natural vein visibility also affect how noticeable these changes are.
Not seeing more visible veins at Week 10 is equally possible and does not tell you whether a pregnancy is developing normally.
Bloating and a Changing Waist at Pregnancy Week 10
You may find jeans or other fitted clothing beginning to feel tighter around Week 10.
The NHS explains that the uterus is around the size of a large orange at this stage, but digestive bloating can also contribute significantly to how the abdomen feels.
Progesterone relaxes smooth muscles, including muscles in the digestive tract. This can slow digestion and contribute to gas, bloating and burping.
A larger-looking abdomen during Week 10 is therefore not simply the size of the developing baby.
Healthy Choices During Pregnancy Week 10
Continue Folic Acid
General pregnancy guidance recommends continuing folic acid through at least Week 12, although individual recommendations can differ.
Avoid Alcohol and Smoking
Avoid alcohol, smoking and recreational drugs during pregnancy. Professional support is available if stopping is difficult.
Eat a Balanced Diet
There is no need to eat for two. Focus on a varied, balanced diet containing nutrient-rich foods that you tolerate well.
Stay Hydrated
Drink adequate fluids, particularly if nausea or vomiting continues.
Review Medications
Do not stop prescribed medications without speaking with the healthcare professional responsible for your care.
Prenatal Care Around Pregnancy Week 10
Pregnancy Week 10 is often an important time for early prenatal care.
Depending on your healthcare system, you may already have had or may soon have an initial pregnancy appointment.
Early prenatal appointments can include discussions about medical history, medications, previous pregnancies, nutrition, lifestyle, screening options and estimated gestational age.
The NHS notes that a first booking appointment commonly takes place between Weeks 8 and 12.
What Might an Ultrasound Show at Pregnancy Week 10?
An ultrasound around Week 10 may show a recognizable developing baby, cardiac activity and spontaneous movement.
It can also provide a crown-to-rump measurement that may help with pregnancy dating.
The NHS notes that dating scans are commonly performed between about 8 and 14 weeks within its maternity-care system.
However, an ultrasound image from an online pregnancy guide cannot be used to interpret your individual scan.
Pregnancy Week 10 and Your Estimated Due Date
Gestational pregnancy weeks are conventionally counted from the first day of the last menstrual period.
Our Pregnancy Due Date Calculator can help estimate an expected due date using relevant pregnancy dating information.
A calculated due date remains an estimate rather than a guaranteed date of birth.
ACOG notes that a first-trimester ultrasound can be used to estimate or confirm gestational age when menstrual dating is uncertain.
What Happens After Pregnancy Week 10?
Pregnancy Week 11 brings another important developmental transition.
In ACOG's gestational timeline, Week 11 begins the fetal stage. Development of the face, limbs, fingers, toes and internal systems continues.
The body begins lengthening and changing proportions while the head remains relatively large.

When Professional Healthcare Guidance Is Important
Online pregnancy guides can explain typical Week 10 development but cannot assess an individual pregnancy.
Seek professional medical advice if you experience heavy bleeding, significant or one-sided abdominal pain, fainting, fever, severe vomiting, dehydration or other symptoms that concern you.
Questions about ultrasound results, pregnancy measurements, medications, persistent nausea or other individual concerns should also be discussed with an appropriately qualified healthcare professional.
Pregnancy Week 10 FAQs
What happens during Pregnancy Week 10?
The head becomes rounder, the elbows can bend, fingers and toes continue lengthening and losing their earlier webbing, and the eyelids and outer ear structures continue developing.
How big is the baby at 10 weeks?
The NHS describes the developing baby at around 30 millimeters from head to bottom, approximately the size of a small apricot.
Is the baby the size of a plum at Week 10?
Fruit comparisons differ between pregnancy guides. Current NHS guidance uses a small apricot comparison, while exact crown-to-rump measurements are more informative than fruit comparisons.
Can the baby move at 10 weeks?
Yes. Tiny spontaneous movements are occurring and may sometimes be visible during an ultrasound.
Can I feel movement at Pregnancy Week 10?
Usually no. The developing baby is still far too small for these movements to normally be felt by the pregnant person.
Can the elbows bend at Week 10?
Yes. Mayo Clinic identifies bending elbows as one of the developmental changes associated with Pregnancy Week 10.
Does morning sickness end at Week 10?
Not necessarily. Some people begin improving, but nausea can still be common at Week 10 and may continue for several more weeks.
Does blood volume increase by 40 percent at Week 10?
Blood volume starts increasing early in pregnancy, but the commonly cited 40 to 45 percent figure represents an approximate overall increase across pregnancy rather than a sudden Week 10 change.
Why are my veins more visible during pregnancy?
Pregnancy increases circulation and blood volume over time, which can make superficial veins more noticeable in some people.
What happens during Pregnancy Week 11?
Week 11 brings continued growth and, in ACOG's gestational timeline, the beginning of the fetal stage. Facial, limb and internal-system development continues rapidly.
