Almost There
Week 11. You are three weeks from the end of the first trimester, two weeks from the NT scan if you have not had it yet, and somewhere between counting down the days and still holding your breath. For many women this week brings a particular kind of suspension: too early to fully exhale, too late to be in the thick of the scariest early weeks.
If the nausea is beginning to ease, you might feel almost guilty for feeling better. If it is not easing, you might feel cheated by every app and article that promised relief "by week 10." Both of these experiences are legitimate, and both are common. The trajectory of nausea varies meaningfully from person to person. Some women feel better by week 9. Some feel unwell until week 14 or 15. A small percentage experience significant nausea throughout pregnancy [1].
What week 11 reliably delivers is remarkable development happening in that fig-sized fetus.
Your Baby This Week
Your fetus measures approximately 1.6 inches (4.1 cm) from crown to rump and weighs about 0.25 ounces (7 grams), roughly the size of a fig [2]. The head is still disproportionately large, accounting for about one-third of total body length, but the body is growing rapidly to catch up.
This week, tooth buds for all 20 primary (baby) teeth are forming beneath the gums [1]. Those teeth will not erupt until after birth, but their foundations are being laid right now. This is one of the reasons adequate calcium intake during pregnancy matters, not for the teeth specifically (they have a dedicated supply), but for your overall bone health as your body prioritizes the developing fetus.
Bone ossification (the process of cartilage hardening into bone) is beginning in earnest [2]. The skeleton is transitioning from flexible cartilage to true bone, starting with the long bones of the arms and legs. Your baby can also hiccup at this stage, though you will not feel these movements for another several weeks.
The fetus can make a fist. Fingernails are just beginning to form at the fingertips [1]. If you could see your baby right now, the profile would be recognizable: forehead, nose, mouth, chin. The ears are moving from the sides of the neck upward toward their final position on the head.
The NT Scan: What You Need to Know Before You Go
The nuchal translucency (NT) scan is typically performed between weeks 11 and 13 and 6 days [4]. If your provider has not yet scheduled yours, confirm this week that it is on the calendar, because the window closes.
The scan itself is an ultrasound, often abdominal at this stage but sometimes transvaginal for a clearer image. The sonographer measures the nuchal translucency, the fluid-filled space at the back of your baby's neck. An increased measurement can indicate a higher risk for chromosomal conditions including Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13 [4].
The NT measurement alone is just one data point. In most practices it is combined with a blood test measuring two proteins: PAPP-A (pregnancy-associated plasma protein A) and free beta-hCG. Together these results form the combined first-trimester screen, which produces a risk ratio, not a diagnosis [3].
Key things to understand before the appointment:
- It is a screening test, not a diagnostic test. It assesses probability, not certainty.
- Most results are normal. The vast majority of NT scans show no increased risk.
- An elevated measurement is not a diagnosis. It is an indication for further evaluation, which might include NIPT (cell-free DNA testing) if you have not already had it, or diagnostic testing such as CVS (chorionic villus sampling).
- NIPT and NT scanning are complementary. Even if you have already had NIPT results, the NT scan provides structural information about your baby's development.
Your Body at Week 11
- Nausea may be beginning to ease. For many women, the gradual improvement begins around now, though the timeline varies considerably [1].
- Dizziness when standing. As blood volume continues to expand, the cardiovascular system is adjusting to circulate significantly more blood. Standing up quickly can temporarily reduce blood flow to the brain, causing lightheadedness. Rise slowly, stay hydrated, and sit back down if you feel dizzy.
- Hair and skin changes. Increased estrogen can make hair appear thicker and shinier as more follicles remain in the growth phase. Some women experience the opposite: dry skin, breakouts, or patches of darkening pigmentation (melasma) on the face.
- Round ligament discomfort. As the uterus grows, the round ligaments that support it stretch. You may notice brief sharp or aching sensations on one or both sides of the lower abdomen, especially with sudden movements or position changes.
- Visible bump forming. Whether you are showing depends significantly on your body, your fitness level, and whether this is your first pregnancy. Both showing and not showing at week 11 are normal.
Exercise at Week 11
If you have been avoiding exercise out of uncertainty, week 11 is a good time to get clarity. ACOG recommends 150 minutes of moderate-intensity aerobic activity per week for healthy pregnant women, the same recommendation as for non-pregnant adults [5]. Walking, swimming, prenatal yoga, cycling on a stationary bike, and low-impact aerobics are all appropriate for uncomplicated pregnancies.
Activities to discuss with your provider first: anything involving contact sports, falling risk, or lying flat on your back for extended periods. Your provider can review your specific situation and give you individualized guidance.
"Everyone says nausea ends at 12 weeks. Mine is getting worse." The "12-week promise" is one of the most repeated and least reliable timelines in pregnancy. For some women, nausea peaks in weeks 11-13 and lingers well into the second trimester. When the expected relief does not arrive on schedule, it can feel like your body is broken or that something is wrong. It is not. Nausea duration varies enormously. If yours is severe enough to prevent eating or drinking, ask your provider about prescription options. You do not have to just endure it.
What MomDoc Wants You to Know
The NT scan appointment is an emotional one for many women. It carries weight. Whatever you are feeling about it, whether you are dreading it, looking forward to it, or trying not to think about it, bring those feelings into the room with you. Your MomDoc provider has supported women through every version of this appointment, including the ones with difficult results, and they are prepared to walk through it with you.
Ask your questions. All of them. Write them down beforehand if that helps. There are no questions too small or too anxious to ask in that room.
The finish line of the first trimester is one week away. Your fig-sized baby has twenty tooth buds and the ability to hiccup. You are nearly through the hardest stretch.
