Week 11 of Pregnancy
Learn about your baby's development and what to expect at 11 weeks pregnant.
Baby's Size This Week
Baby Development at Week 11
- ● Your baby is about 4.1 cm from crown to rump and weighs around 7g — roughly the size of a lime.
- ● The head makes up about half of the body length as the brain continues its explosive growth and differentiation.
- ● Hair follicles are forming all over the body, and the ears are moving to their final position on the sides of the head.
- ● Bone marrow is beginning to produce white blood cells, laying the foundation of the immune system.
- ● The diaphragm is developing, and your baby may already have occasional hiccups visible on ultrasound.
- ● Fingers and toes have separated completely, and unique fingerprint patterns are beginning to form in the skin ridges.
Your Body at Week 11
- ● Nausea may start to gradually decrease as hCG levels plateau and the placenta takes over hormone production.
- ● Bloating and gas continue as progesterone relaxes the smooth muscles of the digestive tract.
- ● Your uterus is now about the size of a grapefruit and is beginning to rise above the pelvic bone.
- ● You may notice increased vaginal discharge (leukorrhea), which is normal and helps prevent infection in the birth canal.
- ● Leg cramps, especially at night, may begin due to changes in circulation and calcium or magnesium levels.
- ● Mood swings may continue, but many women start to feel emotionally more stable as the trimester nears its end.
Week 11 Checklist
- ☐ Complete first-trimester screening (nuchal translucency ultrasound) if planned — the window closes at week 13-14.
- ☐ Begin exploring childcare options early, as quality daycare waitlists can be 1-2 years long.
- ☐ Consider joining a prenatal fitness class or beginning prenatal yoga for safe, guided exercise.
- ☐ Talk to your employer about pregnancy workplace accommodations if your job involves physical demands.
- ☐ Eat calcium-rich foods (dairy, leafy greens, fortified foods, almonds) to support baby's rapidly developing bones.
- ☐ If constipated, increase fiber intake to 25-30 grams daily and consider a fiber supplement after discussing with your provider.
Frequently Asked Questions
When will I start showing?
Most first-time mothers begin to show a visible baby bump between weeks 12-16, though this varies widely. Second-time mothers often show earlier because the abdominal muscles have already been stretched. Factors like body type, muscle tone, and the position of the uterus also affect when a bump becomes noticeable.
Are leg cramps normal during pregnancy?
Yes, leg cramps are very common, especially in the second and third trimesters, but they can start as early as the late first trimester. They are often caused by changes in circulation, increased weight, and possible mineral imbalances. Stretching your calves before bed, staying hydrated, and ensuring adequate calcium and magnesium intake can help. Contact your provider if cramps are severe or persistent.
Is increased vaginal discharge normal?
Yes, thin, milky white, mild-smelling discharge (leukorrhea) is completely normal and often increases during pregnancy. It helps protect the birth canal from infection. However, contact your provider if discharge is green, yellow, foul-smelling, or accompanied by itching, burning, or irritation, as these could indicate an infection.
Can I tell people I'm pregnant at 11 weeks?
This is a personal decision. Many couples wait until after the first trimester (around 12-13 weeks) when the risk of miscarriage drops significantly (to about 2-3%). Others share earlier with close family or friends for support. There is no medical rule — share your news whenever you feel comfortable.
How much calcium do I need during pregnancy?
Pregnant women need 1,000 mg of calcium per day (1,300 mg if under 18). Calcium is critical for your baby's bone, teeth, muscle, and nerve development. If your diet does not provide enough, your body will pull calcium from your own bones. Good sources include dairy products, fortified plant milks, canned salmon with bones, broccoli, kale, and almonds. Many prenatal vitamins contain some calcium, but may not provide the full daily requirement.
