Pregnancy week-by-week: First trimester
This is all so new right now, but don’t worry, mama ‒ this first trimester of your week-by-week pregnancy guide will take you through all you need to know.
From your pregnancy appointments timeline and pregnancy ultrasound schedule to pregnancy milestones and how big baby is during your pregnancy timeline, we’ve got all you need to know about the first trimester.
If you’ve just found out you’re expecting, you might think this is your first week of pregnancy…
Turns out, you’re probably around four weeks pregnant!
Simply put, day one of your pregnancy is calculated as the first day of your last period, so at one week pregnant you’re actually not pregnant at all (yep, really!).
So don’t expect to see anything on a 1-week ultrasound ‒ technically, baby isn’t there yet!
So you may not necessarily be giving birth 40 weeks from today ‒ it could be a little before or after that point, depending on when your last period was.
How big is baby? Well, they could just be the size of an unfertilized egg right now ‒ about 0.004 inches or 0.1 millimeters big, and they may not even be technically conceived yet.
Week 1 of pregnancy symptoms: Similar to your normal period symptoms ‒ a little bleeding (which may be implantation bleeding), mood swings, bloating, and cramps.
🔎 Dig deeper: 1 Week Pregnant: What to Expect
Week 2 of your pregnancy might actually be when you get between the sheets ‒ when baby is conceived and around the time of implantation.
This is likely to be around the same time that you’re ovulating, which is also known as your fertile window ‒ the time in your menstrual cycle that you’re most likely to conceive.
So even though you’re classed as 2 weeks pregnant, your pregnancy week-by-week hasn’t really started yet!
How big is baby? Again, baby might not have even been conceived yet, so they’re just the size of an unfertilized egg… and a budding sperm. So roughly 0.004 inches or 0.1mm ‒ about the width of a strand of hair.
Week 2 of pregnancy symptoms: You might be feeling ovulation symptoms at this point, like an increase in leukorrhea (discharge), cramping, breast tenderness, and you might be feeling… in the mood… 😏
🔎 Dig deeper: 2 Weeks Pregnant: What to Expect
Although it might seem like nothing is happening on the outside, on the inside, you’ve made a baby!
This is where your pregnancy timeline can truly begin.
You recently ovulated and a fertilized egg is sitting happily on the wall of your uterus, gearing up to grow over the next eight months (give or take).
How big is baby? Baby is a teeny tiny zygote right now, turning into a blastocyst ‒ doubling in size to 0.008 inches or 0.2mm.
Week 3 of pregnancy symptoms: Things haven’t really kicked off yet, in terms of pregnancy symptoms week by week, although you may notice a little bloating and a heightened sense of smell and taste.
🔎 Dig deeper: 3 Weeks Pregnant: What to Expect
Some mamas may not know they’re pregnant at this stage, but it could be the point that your period doesn’t show up ‒ one of the first signs of pregnancy.
This might be the point that you try taking a home pregnancy test ‒ a lot of our mamas on Peanut choose a pregnancy test that shows weeks, so you know roughly how far along you are, before your first prenatal appointment.
How big is baby? Your developing baby is now officially an embryo and is the size of a poppy seed ‒ around 0.008 inches or 0.2mm.
Week 4 of pregnancy symptoms: You may not be feeling any different just yet, since early pregnancy symptoms don’t always kick in right away.
🔎 Dig deeper: 4 Weeks Pregnant: What to Expect
By week five, you should’ve missed your period ‒ one of the most obvious signs of pregnancy.
Also, at this point, the level of hCG in your body (aka the pregnancy hormone) is definitely high enough to be detected by a home pregnancy test, so if you haven’t had one so far, try now!
How big is baby? Baby’s jumped in size now, measuring in at around 0.06-0.08 inches or 1.5-2mm long ‒ about the size of the width of a piece of spaghetti.

Pregnancy appointments timeline
So now we know your full pregnancy week-by-week schedule (if we can really call it that!), let’s break down your pregnancy ultrasound schedule.
It’s worth noting here that not every pregnancy will have all of these appointments ‒ some pregnancies are classed as ‘high risk’, so would require more check-ups and additions to your pregnancy appointments timeline.
- First pregnancy appointment: Between weeks 8 and 12, you’ll have your first pregnancy appointment and ultrasound. It’s worth booking this in as soon as you find out you’re pregnant. Your doctor will also run through how baby’s developing, what to expect, any lifestyle or dietary changes they recommend, along with any potential risks or things to be aware of during your pregnancy.
- Second pregnancy appointment: Once you’re in your second trimester, usually between weeks 16 and 20, you’ll have your second pregnancy appointment and ultrasound. You usually book this in during your first appointment. This is also the time that you can find out baby’s sex, if you want to.
- Third pregnancy appointment: If this is your first pregnancy, you’ll likely have an appointment at around 25 weeks, although it’s not likely that you’ll have an ultrasound at this point in your pregnancy timeline.
- Fourth pregnancy appointment: You may also have another pregnancy appointment at around 28 weeks, to check baby’s growth and your physical wellbeing.
- Fifth pregnancy appointment: At about 30 weeks, you may have another appointment and possibly an ultrasound ‒ again, to check on baby’s growth and measure things like your blood pressure and protein levels.
- Sixth pregnancy appointment: Depending on how your pregnancy has been so far, your doctor may recommend another ultrasound and pregnancy appointment at 36 weeks. Then, from about 36 weeks, you’ll probably have weekly appointments, just to make sure you and baby are doing well ‒ after all, pregnancy is exhausting!
- Seventh pregnancy appointment: If baby’s not showing any signs of leaving the cozy home you’ve made for them over the past 9 months, your doctor may recommend a final ultrasound at 40 weeks, to check up on how baby’s doing and figure out the next best steps ‒ basically, getting baby outta there!
Pregnancy week-by-week FAQs
Still got some burning questions about your pregnancy countdown? We’ve got you covered.
How many weeks is a pregnancy?
Just how many weeks is full-term pregnancy?
Roughly about 40 weeks, although some babies are born before that (preemie babies) and some are born after then.
If baby is born after 42 weeks of your pregnancy, they’re classed as post-term, and you’ll usually be induced or have a c-section.
Is pregnancy 40 weeks or 9 months?
Sort of… both. Although 9 months is about week 39 of your pregnancy timeline, and some babies can be born at this time, other pregnancies can be a little longer.
Is a 42-week pregnancy normal?
Yes, a 42-week pregnancy is totally normal ‒ in fact, around 35% of babies are born between weeks 41-42.
Is 37 weeks full term?
While babies can be born at 37 weeks and be totally healthy, that’s classed as early term.
Baby will be full-term from 39-40 weeks.
What’s the best pregnancy test with weeks indicator?
Looking for a pregnancy test that shows weeks?
Well, according to our mamas of Peanut, the best of all the pregnancy tests that show weeks is the Zioxx Digital Early Result Pregnancy Test Kit with Smart Weeks Indicator.
It’s pretty accurate in estimating how many weeks your pregnancy is, but for the most accurate result, it’s best to see your doctor for your first ultrasound.
What are the key milestones in pregnancy?
Pregnancy milestones differ from mama to mama ‒ after all, the first time you get morning sickness might not be a cherished memory for every mama.
But here’s a list of all the key pregnancy milestones for you to keep track of:
- Your positive pregnancy test.
- Telling your partner, friends, or family.
- The first time you get pregnancy nausea.
- Your first pregnancy appointment.
- Announcing your pregnancy on social media (if you choose to).

What is the halfway point in pregnancy?
The halfway point in your pregnancy is likely to be between weeks 20-24.
When do I start showing?
It depends on your body type and how many babies you’re carrying, but generally, you can expect to be showing from about 16 weeks of your pregnancy.
Which trimester is the most critical?
Well, all trimesters are important, as baby develops in different ways through each of them.
But the first trimester is when baby starts to grow, so the first trimester can be what sets them in good stead for the rest of the pregnancy.
What week is most critical in pregnancy?
It’s hard to define one specific week that’s most critical in your pregnancy ‒ but around week 3 or 4 can be critical, as that’s likely to be when conception and/or implantation happens.
Which trimester is physically the easiest on the mother?
So what is the easiest trimester? Well, it’s a tricky question, because different pregnancies affect different mamas in different ways.
But, very generally speaking, the second trimester is the ‘nicest’ trimester for some mamas ‒ less of the anxiety and nausea of the first trimester (sometimes) and not as much of the discomfort as the third trimester.
At what week do most pregnancy symptoms start?
It depends ‒ some mamas have pregnancy symptoms as early as 4 weeks pregnant, while others don’t feel any different until about 8 weeks pregnant.
