In week five many people feel the first clear symptoms: nausea, drowsiness, tender breasts. At the same time an organizational task appears — the first blood tests and the first ultrasound. The good news is that preparing for both takes a few minutes, and a good plan for nausea and fatigue genuinely changes the quality of your day.
What to do in week 5
- Check which tests require coming fasted.
- Ask how to prepare for the ultrasound.
- Write down questions for the first visit and for the test.
- Arrange help with cooking for the days with nausea.
- Plan two short rest breaks into each week.
How to prepare for a blood test
Ask at the front desk whether any of the tests require coming fasted, and fit your visit time around it. Drink water before the blood draw — it is often easier to find a vein then, and you feel better too. Bring a list of the medications and supplements you take, including ones bought without a prescription. If blood draws are hard for you, tell the staff — you can usually choose a more comfortable position or take a longer moment to rest.
- Check which tests you come to fasted and which do not require it.
- Bring your ID and the referral, if one was issued.
- Prepare a list of medications and supplements with their names.
- Plan something to eat after the draw so you do not leave hungry.
How to prepare for the first ultrasound
Before the first ultrasound, ask whether the scan will be done through the abdominal wall or transvaginally — this determines how you prepare your bladder. Wear something easy to take off and put back on, and if the clinic asks, bring a pad or towel. Bring results of earlier tests, if you have them. During the scan, ask for a brief explanation of the image and write the key information down in your note right away.
Nausea and fatigue — a plan for the day
Nausea in the first trimester often gets worse on an empty stomach and in response to smells. It helps to eat small portions more often and to keep something bland at hand, such as crackers or a banana. Cooking can be difficult then, so ask someone close to help and air out the rooms. Treat fatigue as a signal, not a weakness: plan a short nap and one task fewer.
- Eat small portions more often instead of a few large meals.
- Keep a snack by the bed and eat something before getting up.
- Air out the rooms and avoid strong smells.
- Plan a short nap and a shorter list of duties.
- Drink water throughout the day, in small amounts.
It is also worth preparing for the conversation at the visit itself. Describe your symptoms in your own words and say how they affect your day: whether you manage to eat and drink, how you sleep, and whether you leave the house. The medical staff will ask follow-up questions and assess whether further diagnostics are needed. You do not have to draw conclusions or suspect specific causes — an honest description of what is happening is enough.
Tip
Note on your phone which foods trigger nausea the least — a few days of observation gives you a practical list for harder days.
Referrals and registering for tests
Some tests in pregnancy are publicly funded, while others come with conditions worth knowing before registering. Ask which tests you need a referral for and how long it is valid. Find out whether you can combine several draws into one visit instead of multiple trips to the collection point, and what the waiting times look like at your clinic. If you use the online patient account, check whether referrals and results are visible there.
A list of questions for the first pregnancy visit
- Which tests are needed now, and which only in the coming weeks?
- How should I take the medications and supplements I already use?
- When and where should the ultrasound be done, and how do I prepare for it?
- Which symptoms should prompt me to call the clinic?
- When should the next visit be booked, and whom do I contact between visits?
Everyday life: travel and commutes
Travel in the first trimester is mostly a matter of organization. Plan your route so that breaks and bathroom stops are possible, and bring water and a snack. If you are traveling farther, ask the staff whether it is worth carrying your records with you and how to reach the clinic if needed. Save the registration number so it is available even without internet access.
When to contact a doctor
- • If you cannot keep fluids down or vomiting makes eating impossible, call your doctor or midwife.
- • Dizziness, fainting, or very little urine output is a reason to contact the clinic.
- • In a life-threatening situation, call 112.
When to call a doctor or midwife
- • Vomiting that prevents you from taking in fluids.
- • Dizziness or fainting.
- • Very little urine output while feeling unwell.
In a life-threatening situation call 112 or go to the nearest maternity hospital admission room — do not wait for a follow-up appointment.
Week 5 in detail
Week 5: how your baby grows — A sesame seed
Week five is one of the most exciting stages. Your little one is the size of a sesame seed and measures about 1.5 mm, but right now something extraordinary begins: the cardiac tube — the precursor of the heart — starts to pulsate. It's the beginning of the heartbeat you'll see and hear on an ultrasound in a few weeks.
Development in week 5
- The neural tube is forming — the foundation of the brain and spinal cord.
- The rudiments of the major organs appear.
- The cardiac tube begins to contract — the first beats of the circulatory system.
Tip
Midwife's tip: this week folic acid supplementation is key, because the neural tube is developing right now. It's your most important 'job' at this stage.

Week 5: tests and symptoms — Your first antenatal appointment
Week five is when the hormones start 'talking': you may feel nauseous, have tender breasts, a sharpened sense of smell and an overwhelming need to sleep. That's a completely normal reaction to rising hCG, estradiol and progesterone. If you haven't yet — book your first pregnancy appointment.
Your first appointment — what to expect
- The doctor will confirm the pregnancy (beta-hCG, ultrasound).
- They will take your history: last period, conditions, medications you take.
- They will order initial tests: blood count, TSH, glucose, blood group, and if there's risk — toxoplasmosis and rubella.
How to ease nausea this week
- Eat small meals every 2–3 hours so your stomach is never empty.
- Some women find ginger helps — ask your doctor or midwife whether it's recommended in your situation and in what form.
- Avoid strong smells and rich, heavy foods.
When to contact a doctor
- • If you vomit more than 3 times a day and can't keep fluids down — see a doctor. You may need help.
Tip
Midwife's tip: keep crackers or a banana by your bed and eat them before you get up — an empty stomach makes morning nausea worse.

Week 5: The heart starts beating — what you can do today
Week five is a good moment to build a simple daily routine you'll lean on throughout pregnancy. Build it without pressure — consistency matters more than perfection.
Supplementation — your foundation
- Folic acid / folates — ask your doctor or midwife about the right product and how to take it.
- Vitamin D — whether to take it and in what form is decided by your doctor.
- DHA (omega-3 fatty acids) — ask whether supplementation is recommended in your case.
Getting ready for the week ahead
- Book your first pregnancy appointment (ideally weeks 6–8).
- Start noting symptoms and questions — they'll come in handy at the doctor's.
- Plan more frequent, smaller meals to ease nausea.
Tip
Midwife's tip: if nausea makes eating hard, focus on what stays down — you don't have to eat for two. In the first trimester your calorie needs don't rise significantly.
