First trimester
11 weeks pregnant
Baby is about the size of a lime.
Week 11 of 40 · in your first trimester · Updated
Your baby this week
Baby can hiccup, kick, and stretch — though you can't feel it yet.
- The diaphragm is forming, which causes practice hiccups (you won't feel them).
- Fingers and toes are fully separated. Baby is constantly stretching and kicking.
- Tooth buds are forming under the gums.
Your body this week
Your hair and nails might start growing faster thanks to hormones.
- Increased estrogen makes hair appear thicker and grow faster, while nails grow more quickly too.
- Your gums may bleed more easily — pregnancy gingivitis is common.
- Some women still have nausea while others feel mostly better.
Common symptoms
- Faster hair and nail growth
- Bleeding gums
- Skin changes
- Heartburn
- Increased thirst
Things to do this week
- Brush gently and floss to manage gum sensitivity
- Drink plenty of water
- Apply lotion to belly to prevent stretch marks (though genetics is the main factor)
For partners this week
Pick up the slack
- Take on a bigger share of the housework without keeping score.
- Be the snack keeper — small, frequent bites still help.
Typical visits around this week
Based on a typical schedule in Ontario. Your doctor or midwife sets the actual timing.
First prenatal visit
Weeks 6–12
Book with your doctor or midwife as soon as you know you're pregnant. This is usually the longest visit: your health and family history, medications, blood pressure and weight, and routine blood and urine tests (including your blood type and Rh factor). Your provider will also talk about your due date and the screening options ahead.
Questions to ask →Questions to ask ↑
- When is my estimated due date, and how was it worked out?
- Are my current medications and supplements okay to keep taking?
- Who will care for me during pregnancy and birth, and where would I give birth?
- Who do I call with questions or worries between visits?
- Which vaccines should I plan for this pregnancy?
Dating ultrasound
Weeks 7–12
An early ultrasound that measures the baby to confirm how far along you are. Dating is most accurate between about 7 and 12 weeks, and the scan also confirms the pregnancy is in the uterus.
Questions to ask →Questions to ask ↑
- Does this scan change my due date?
- Can my partner come into the room?
- Do I need a full bladder, and how should I prepare?
- When will my provider get the results?
Prenatal genetic screening
Weeks 11–14 · if it applies to you
Screening for chromosome differences is offered to everyone, and whether to have it is your choice. In Ontario, enhanced first trimester screening (eFTS) is publicly funded and combines a blood test with a nuchal translucency ultrasound at about 11–14 weeks. NIPT, another blood test, may be publicly funded or private-pay depending on your situation. Your provider will explain the options.
Questions to ask →Questions to ask ↑
- Which screening options are available to me, and which are covered?
- Am I eligible for publicly funded NIPT?
- What can these tests tell us, and what can't they?
- When and how will we get results?
- What would happen next if a result comes back higher-chance?
Coming up
Routine check-ups (about every 4 weeks)
Weeks 12–28
Check-ups are often about every 4 weeks until around 28 weeks. Your provider usually checks your blood pressure, weight and urine, listens to the baby's heartbeat and measures your growing belly. Some people need more visits.
Questions to ask →Questions to ask ↑
- Is my blood pressure and weight gain on track?
- Is this symptom I've been having normal?
- What should I be doing about exercise, work or travel right now?
- What's coming up before my next visit?
A flu shot and a COVID-19 vaccine are recommended at any stage of pregnancy. The flu shot is given during flu season, so the timing depends on when you're pregnant.
When to call your doctor or midwife
Bleeding, fluid leaking, a bad headache or vision changes, or baby moving less than usual all need a call. See the warning signs and who to call →
