what's happening in your body
Many people feel a noticeable lift in energy as the first trimester nears its end. Nausea may finally start easing for some.
symptoms at 11 weeks
- Easing nausea for some
- The tide begins to turn this week for a lucky portion of people. If yours still rages, the average fade point is weeks 12 to 16 — you are close.
- Increased appetite returning
- As aversions loosen their grip, genuine hunger can reappear. You need no extra calories in the first trimester, so eat to appetite rather than for two.
- Feeling warmer
- A higher metabolic rate and increased blood flow can leave you running warm and sweating more easily. Layers and a water bottle are the fix.
- Leg cramps beginning
- Sudden calf cramps, often at night, can start around the end of the first trimester. Stretching the calf before bed and staying hydrated reduce them.
- Dizziness on standing
- Blood pressure often reaches its low point around now. Rise slowly from bed and chairs, and sit down at the first hint of a wobble.
- Breast growth continuing
- Many people go up a cup size by the end of the first trimester. A professional bra fitting now saves weeks of discomfort.
gentle tips
- If you've been hiding the pregnancy, plan when to share it.
- Restart gentle exercise if nausea is easing — walking or prenatal yoga.
- Schedule the 11–13 week NT scan if your provider offers it.
- Keep up the prenatal vitamin and folate-rich foods.
- Sleep on your side when possible — pillows make it easier.
your week 11 checklist
- Attend your dating scan this week or next if scheduled — bring your partner and your notes
- Decide your announcement plan for after the scan: who hears first, and how
- Get fitted for new bras — underwires are fine if they fit well
- Look into antenatal course options (NCT, hospital-run, online) — popular ones book up months ahead
what to expect next
Around week 12 you can sometimes hear the heartbeat with a handheld Doppler at prenatal visits — emotional first listen.

What should I do at 11 weeks pregnant?

Restart gentle exercise if nausea is easing — walking or prenatal yoga. Schedule the 11–13 week NT scan if your provider offers it.
What does the 12-week dating scan actually check?
The sonographer measures the baby from crown to rump to date the pregnancy accurately and set your due date, checks the heartbeat, counts babies, and looks at early anatomy. If you have opted for combined screening, the fluid at the back of the baby's neck (nuchal translucency) is measured too. It is also simply the first proper look at your baby — most parents find it the emotional milestone of the trimester.
Can the dating scan change my due date?
Yes, and it often does — the crown-rump measurement at 11 to 14 weeks is more accurate than period dates, especially with irregular cycles. If the scan date differs from your period-based date by more than a few days, the scan date wins and your due date is officially adjusted. From then on, all your care runs off the scan date.
Is it too early to feel the baby move at 11 weeks?
The baby is genuinely moving — squirming, stretching, even somersaulting — but at around 4 cm long it is far too small for those movements to register through the uterine wall. First felt movements (quickening) typically arrive between 16 and 22 weeks, later for first pregnancies and anterior placentas. Anything you feel at 11 weeks is almost certainly digestion.
