Week three is the time just before or right after conception — if fertilization has happened, it takes place without any noticeable signals. A pregnancy test has nothing to detect yet, so there is no point in taking one too early. Spend this week on organizational preparation: deciding where you will register and gathering questions for your first conversation.
What to do in week 3
- Decide which gynecologist or midwife you will register with.
- Write down the registration number and the rules for booking visits.
- Check whether the clinic requires a referral.
- Prepare a list of questions before your first contact.
- Note the date of your last period and your cycle length.
The time before conception — what it means in practice
Fertilization, if it happens, takes place in the fallopian tube and gives no recognizable symptoms during the first days. Cells divide and travel toward the uterus while your body works in the background. Feeling nothing at all this week is a normal, expected state — not a sign that something went differently.
Where you will register and how to arrange it
Before a positive result appears, it helps to know whom you will call. Choose the gynecologist or midwife closest to you and check how registration works — by phone, online, or in person. At the front desk, say briefly that you suspect you may be pregnant and ask about the earliest first appointment. If the clinic requires a referral, ask how to get one and who can issue it.
- Write down the registration phone number and its opening hours.
- Check whether the clinic works within insurance or privately.
- Find out whether a referral from a family doctor is needed.
- Ask what to bring to the first visit and how much time to set aside.
Questions worth having ready
- When is the best time to take a pregnancy test if my period is late?
- Do any of my medications need changing right now?
- Which symptoms should prompt me to get in touch sooner?
- When should I come for the first visit if the test is positive?
Preparing these few questions takes a few minutes and changes the course of the visit. Staff then answer what genuinely interests you instead of following their own script. If you do not know where to start, list everything that comes to mind and then mark the three most important points — you can add the rest next time. It is also worth writing down the answers, because in the office it is hard to remember every detail.
Tip
Keep your questions in a note on your phone and add new ones the moment they appear — do not leave it until the day of the visit.
Whom to tell about trying, and when
At this stage there is no result to share yet, so the question "is there any news" will keep coming back. Decide together with someone close whom you tell about trying and in what words. You can also prepare a sentence that ends the probing — for example, a request for patience. Remember that telling family and telling work are two separate decisions, and you can make them at different times.
What to bring to the first visit
- Your ID and insurance number, if you know it.
- The date of your last period and the length of your last few cycles.
- A list of medications, supplements, and herbs you take.
- Existing test results together with the dates they were taken.
- A note with questions and space for the answers.
Everyday life without pressure
Heat, cold, work, and commutes are organizational topics that are easy to blow out of proportion. Plan layered clothing, comfortable shoes, and water in your bag — small things that genuinely improve your day. If your commute to work is long, check whether some tasks can be done remotely or at different hours. Talk to your doctor or midwife about everyday changes that concern your health, not just your loved ones.
What can wait
You do not need to choose a hospital, plan leave, or assemble baby supplies now — those decisions make sense later, when more is known. Put off repeating a pregnancy test day after day as well: a negative result at this early stage settles nothing, and rushing only raises tension. If you do not know when to retest, ask the staff instead of guessing. It is also worth noting how you will get to the clinic and how long the trip takes — it makes planning visits and tests easier.
When to contact a doctor
- • Severe one-sided lower abdominal pain with bleeding or dizziness requires contacting a doctor.
- • If you feel very unwell, do not wait for your scheduled visit — call the clinic.
- • In a life-threatening situation, call 112.
When to call a doctor or midwife
- • Severe one-sided lower abdominal pain.
- • Bleeding with dizziness or fainting.
- • Fever or feeling unwell that is getting worse.
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 3 in detail
Week 3: how your baby grows — A poppy seed
The third week is when the most happens — even though you can't feel it yet. A sperm meets the egg, a zygote forms (the first cell of your future baby), and it starts dividing at a dizzying pace while travelling towards the uterus.
From zygote to morula
- Fertilisation happens in the fallopian tube within ~24 hours of ovulation.
- A single cell divides into 2, 4, 8... forming a cluster of cells called a morula.
- The zygote's genetic material is already set — half from mum, half from dad.
Tip
Midwife's tip: this week the most important thing is to give yourself peace. Fertilisation is a microscopic miracle that happens without your involvement — all you need to do is take care of yourself.

Week 3: what's happening in your body
In the third week of your cycle your body is working at full speed, but the signals are so subtle that you usually don't notice them. The zygote is travelling through the fallopian tube, and you may feel a light ovulation twinge — or nothing at all. Implantation into the uterine lining will only happen in a few days.
What to watch for
- Having no noticeable symptoms this week is completely normal.
- Very light around-ovulation spotting or mild lower-belly tension is possible.
- Your body has started producing progesterone, which will support the pregnancy.
When to contact a doctor
- • If you get severe, one-sided lower-belly pain together with bleeding — see a doctor (suspected ectopic pregnancy needs to be assessed).
Tip
Midwife's tip: if you suspect you may have conceived, treat alcohol and stimulants as a 'no' from today — it's the safest decision for the future.

Week 3: Fertilisation — what you can do today
The third week calls for patience: fertilisation has (possibly) already happened, but a pregnancy test won't show anything yet. The most sensible thing you can do is live as if you were pregnant — to give this start the best chance.
Your tasks for this week
- Avoid alcohol and cigarettes — even before the result is certain.
- Keep taking folic acid and stay hydrated.
- Prioritise rest and stress reduction — cortisol doesn't help your chances.
What not to overdo
- Don't test too early — there's a risk of a false negative.
- Don't drastically change your diet without a reason — dieting at this stage isn't recommended.
- Don't worry about a lack of symptoms.
Tip
Midwife's tip: if you feel the need to do something — tidy up, set up a cosy corner for resting. Rushed action helps less than self-care.
