Trimester 1
Pregnancy Week 11
Your baby is about the size of a fig
Your baby, now a fetus, measures about 4.1 cm from crown to rump and weighs roughly 7 grams, about the size of a fig. The head still looks large compared to the body, but the body keeps lengthening quickly.
Baby development
What does my baby look like?
Your baby is now roughly the size of a fig and looks a little more like a baby with each passing day.
The fingers and toes are beginning to separate. Tiny nail beds are forming, the ears are moving toward their spots on the sides of the head, and the eyelids are settling into place. The nostrils at the tip of the nose are starting to open, and inside the mouth you can make out the tongue and palate.
What's happening with your baby this week?
All of your baby's body parts are becoming more defined. Hair follicles are beginning to form. Taste buds are developing, and the organs are entering their maturation process.
The diaphragm has formed in the chest cavity; this structure separates the heart and lungs from the digestive system. Your baby's heart may beat somewhere between about 110 and 160 times per minute. Even though your baby is moving inside the womb, you probably can't feel those movements just yet.
Your body and changes
What's happening in my body?
As your belly starts to become a bit more noticeable, your muscles and ligaments may stretch. This can cause aches around your abdomen. If the pain is significant or it worries you, reach out to your doctor.
Your body is now circulating far more blood than ever before. This shift can leave you feeling warm, sweaty, or occasionally lightheaded. Where the yolk sac once nourished your baby, the placenta is now beginning to take over that job. During this transition, hormones can bring on fatigue and mood swings.
Digestion and heartburn
Constipation, gas, and bloating are common in pregnancy because of hormonal changes that can slow digestion. Drinking water throughout the day, eating plenty of fiber, and staying safely active can all help.
Heartburn may also start around this time. It's often described as a burning feeling that spreads from below the breastbone up toward the throat. Eating smaller meals, cutting back on fatty and very spicy foods, not lying down right after eating, and avoiding too much fluid with meals can bring some relief.
Fatigue, discharge, and food aversions
Pregnancy fatigue can still be strong this week. It can help to make rest a priority, go to bed earlier, take short naps, and lighten unnecessary loads.
Vaginal discharge may increase due to rising estrogen. Healthy discharge usually looks clear or milky white and has a mild odor. If you notice a foul smell, itching, pain, or a gray, yellow, or green color, check with your doctor.
Food cravings and food aversions are also common during these weeks. A heightened sense of smell and hormonal changes can contribute to them. For most people, this eases up as they move toward the second trimester.
Headaches, your belly's appearance, and weight
Headaches in the first trimester can be linked to hormones, stress, lack of sleep, nasal congestion, allergies, or dehydration. Noticing your triggers, staying well hydrated, getting light exercise, and, if needed, using a suitable pain reliever with your doctor's approval can all help.
If you don't notice a distinct baby bump yet, don't worry. Every woman starts to show at a different time. The uterus begins to rise above the pelvis around week 12; for some this is noticeable earlier, for others later.
Weight gain in the first trimester varies from person to person. It's also possible to gain little because of nausea or a reduced appetite.
Skin changes
In pregnancy, you may notice your nipples and areolas darkening. Hormones can also cause your skin to darken in patches or more broadly. The dark line running down the middle of your belly is called the linea nigra and is usually nothing to worry about.
Symptoms
Symptoms you may notice this week
The symptoms you may notice this week vary from person to person. They can include:
- headache
- fatigue
- mood swings
- heartburn
- mild cramping
- increased vaginal discharge
- food aversions
- bloating and gas
- feeling warm
Mild cramping can occur during these weeks. But if the cramping is severe or comes with bleeding, contact your doctor.
Nutrition
If you're dealing with bloating or constipation, smaller, more frequent meals can make digestion easier. Whole grains, fruit, vegetables, and enough fluids all help.
Caffeinated drinks can have a diuretic effect, so it's important not to rely on them alone to meet your fluid needs. When it comes to alcohol during pregnancy, the safest approach is to avoid it completely.
Tips and exercise
What to expect from your first scan?
The first ultrasound is usually done between 8 and 14 weeks. This scan can be used to assess how far along you are and, in some cases, to carry out additional checks such as a nuchal translucency measurement.
Sexually transmitted infections and long-term conditions
If you or your partner are at risk for a sexually transmitted infection, talk it over with your doctor. If you have a long-term condition or take medication regularly, work out your pregnancy monitoring plan together with your doctor. Don't stop any medications you take regularly without checking with your doctor first.
Things to keep in mind in daily life
Because your immune system can be more sensitive during pregnancy, paying attention to hand hygiene is important. Wash your hands often, and use an alcohol-based hand sanitizer when needed.
Gum sensitivity and bleeding can increase during pregnancy. Brushing regularly, flossing, and keeping up with routine dental checkups help protect your oral health.
You may notice a metallic taste in your mouth. Citrus drinks, or tart flavors if your stomach can tolerate them, may ease this feeling for some people. If your skin has become dry, choosing shorter, warm showers over long, very hot ones and using gentle cleansers and moisturizers can help.
Good to know
By the end of this week, only a short time remains until the second trimester. Some moms-to-be feel warmer, while others chill more easily. Dressing in layers and drinking enough fluids can be soothing.
To keep your energy up, you might reach for nourishing little snacks. Resting, sharing your feelings with someone you trust, and easing your daily expectations a bit can all help you get through this stretch more comfortably.
