Our Baby Journey11 weeks pregnant
11 weeks pregnant is about 2½ months. It falls in the third month of pregnancy. You are in week 11 of 40, in the first trimester. Here is what is happening with your baby and your body this week.
Your baby is about the size of a fig.
Length: about 4.1 cm (1.6 in) from crown to rump · Weight: about 7 g (0.25 oz)
Your baby at 11 weeks
The head is still large compared with the body. Tooth buds are forming, and the baby can open and close its hands.
Your baby now has distinct fingers and toes, and the webbing between them has disappeared. Tiny nail beds are starting to form at their tips, and hair follicles are appearing in the skin. The bones of the face are taking shape, and the ears are moving up from the neck toward the sides of the head.
Inside, the diaphragm, the muscle that will later help your baby breathe, is forming. The baby is making small, jerky movements and may even hiccup, although you won't feel any of this for weeks yet. The external genitals are beginning to develop, but they still look very similar in boys and girls, so the sex usually can't be seen on an ultrasound at this stage.
The placenta is also growing quickly and is getting ready to take over most of the hormone production that has supported your pregnancy so far.
Your body at 11 weeks
Nausea may begin to ease for some people. Your energy may slowly return.
As the placenta gradually takes over hormone production toward the end of the first trimester, some people find their nausea and tiredness start to settle. Others feel little change yet, which is also normal. Your blood volume keeps rising, which can make you feel warm or a little lightheaded. Progesterone slows your digestion, so bloating, gas, and constipation are common around now, and some people notice early heartburn. You may also see a faint darkening of the skin around your nipples or notice veins becoming more visible on your chest and belly.
Your belly at week 11
In month 3 (weeks 9–13) most people still don't look pregnant. Around 12 weeks the uterus rises out of the pelvis, and its top can be felt just above your pubic bone.
Belly size and shape vary a lot depending on your build, whether this is your first pregnancy, your baby's position and the amount of amniotic fluid. At checkups your doctor or midwife may measure your fundal height to track your baby's growth, and may arrange an ultrasound if the measurement is quite different from what they expect.
Symptoms at 11 weeks pregnant
- Nausea that may be starting to ease
- Bloating and constipation
- Early heartburn or indigestion
- Tender, fuller breasts
- More visible veins on the chest and belly
- Mild headaches
Checkups around week 11
Many people have a dating or first-trimester scan between about 10 and 14 weeks. Combined screening for conditions such as Down syndrome (a nuchal translucency ultrasound plus a blood test) is usually offered from about 11 weeks, and cell-free DNA testing (NIPT) can be done from 10 weeks. If a diagnostic test is recommended, chorionic villus sampling (CVS) is typically done between about 10 and 13 weeks. Exact timing and what is offered vary by country and clinic.
Tips for week 11
- Eat iron-rich foods such as lean meat, beans, lentils, and leafy greens.
- Pair iron-rich foods with vitamin C to improve absorption.
- Keep up with your prenatal vitamin.
Common symptoms in the first trimester
The first trimester runs from week 1 to week 13. It is when your baby's major organs, spine and heart form, and when many people feel the most tired and nauseous. Not everyone has every symptom, and it is normal for symptoms to come and go. Common ones include:
- Nausea and vomiting (morning sickness), which can happen at any time of day
- Tiredness and needing more sleep
- Tender, swollen breasts
- Needing to urinate more often
- Food aversions or cravings and a metallic taste
- Mood swings
- Light spotting around implantation

Frequently asked questions
How big is my baby at 11 weeks pregnant?
At 11 weeks pregnant, your baby is about the size of a fig. That is about 4.1 cm (1.6 in) from crown to rump, weighing about 7 g (0.25 oz).
How big is my belly at week 11 of pregnancy?
In month 3 (weeks 9–13) most people still don't look pregnant. Around 12 weeks the uterus rises out of the pelvis, and its top can be felt just above your pubic bone. Bump size, shape and when you start to show vary a lot from person to person.
When does morning sickness usually stop?
For many people, nausea starts to improve toward the end of the first trimester, often somewhere between weeks 12 and 16. For some it fades gradually, and for a smaller group it lasts longer. If you can't keep food or fluids down, are losing weight, or feel dizzy and dehydrated, talk to your doctor or midwife, as severe vomiting needs treatment.
Can I find out the baby's sex at 11 weeks?
Not reliably by ultrasound. The external genitals are still developing and look very similar at this stage. A cell-free DNA blood test (NIPT), which can be done from 10 weeks, can usually report the sex chromosomes if you choose to find out. Most people who want to know by ultrasound wait for the anatomy scan, usually around 18 to 22 weeks.
Should I use a home Doppler to hear the heartbeat at 11 weeks?
Most health organizations advise against relying on home Dopplers. Early in pregnancy the heartbeat can be hard to find even with professional equipment, which can cause needless worry, while hearing a heartbeat can also give false reassurance if something is wrong. Your provider may check the heartbeat at your visits. If you are worried about your pregnancy, contact your doctor or midwife rather than checking at home.
What trimester is 11 weeks pregnant?
Week 11 is in the first trimester, which covers weeks 1 to 13.
How many months is 11 weeks pregnant?
11 weeks pregnant is about 2½ months. It falls in the third month of pregnancy. The third month covers weeks 9 to 13. Pregnancy is about 40 weeks, or roughly 9 months, counted from the first day of your last period.
