First Trimester Pregnancy Symptoms: Weekly Guide & Tips

Congratulations! You’re pregnant. Whether you’ve just spotted those two pink lines or you’re a few weeks in, the first trimester can be an exciting — and, at times, overwhelming — journey. It’s a whirlwind of emotions, changes and, let’s face it, some very strange symptoms. But don’t worry! We’ve spilled it all out for you, week by week, so you know what’s happening and how to deal. From nausea to fatigue, cravings to aversions, we’ve got you covered. Discover first trimester pregnancy symptoms with solutions and tips for each week to help you navigate early pregnancy with confidence and ease. So, get a snack (unless you’re still feeling queasy) and let’s get started!

Week 1–2: The Starting Line

Okay, technically, you’re not pregnant at this point. The first two weeks is counted from the first day of your last period. It’s all about ovulation and preparing for the big moment — fertilization. Your body is preparing, releasing an egg, sparking the miracle that’s about to unfold. You may not be experiencing any symptoms yet, but your body is beginning to work behind the scenes.

Women are strong, strong, terribly strong. We don’t know how strong until we’re pushing out our babies.

Week 3–4: The Big News

And this is when the magic occurs—fertilization! At week 4, your baby is still just a handful of cells (called a blastocyst) nestled into your uterine lining. You may not feel much yet, but some moms get “implantation symptoms,” such as slight cramping or spotting. Oh, and hormones? They’re revving up.

Symptoms:
Light spotting (not to freak out—it’s normal!).
Tender breasts.
A sudden urge to take a nap early in the afternoon.
Solutions:
Rest, rest, rest! (Seriously, this is your body’s pretty clear way of saying, “Slow down.”)
So the first step is to wear a comfy bra for that breast tenderness. Farewell, underwire; welcome, stretchy fabric.

Week 5: Hello, Hormones!

On the fifth week, most women start to experience strong early signs of pregnancy. Hormones such as hCG (the pregnancy hormone) and progesterone are on the rise. You might feel… different. Or your favorite coffee smells bad now. Or you find yourself weeping over commercials. Totally normal.

Symptoms:
Morning sickness (ugh, or all-day sickness).
Fatigue that bears down with the weight of a freight train.
Mood swings — welcome to the emotional rollercoaster!
Solutions:
For nausea: Keep saltines on your nightstand, nibbling one before you hop out of bed. Ginger tea works wonders too!
To Combat Fatigue: Sleep as You Can. Seriously. Your new best friend are power naps.
For emotional ups and downs: Be gentle with yourself. Cry it out if you need to! (Blame those hormones, not yourself.)

Week 6: The Struggle of Nausea Is Real

Welcome to week six — the week when nausea tends to shift from “Hmm, I feel off” to “Oh no, I can’t even look at food.” Your baby’s the size of a lentil at this point, but they’re already causing huge changes in your body. Those changes? They come with symptoms. 

Symptoms:
Nausea (again).
Food aversions.
Extra olfactory abilities (which, sadly, is not as exciting as it sounds).
Solutions:
Be committed to the small and incycler” Think of plain toast, rice or applesauce.
Stay away from strong smells (which might require you asking your partner to do the cooking for a bit).
And carry mints or lemon candies to settle your stomach when you’re on the go.

Week 7: The Fatigue Olympics

If there were an Olympic sport called pregnancy fatigue, you’d finish all the way in first place by week seven. Your body is moving into overdrive to accommodate that growing baby (now, as a blueberry). And although you may feel worn out, your baby is hard at work developing important organs like the brain and heart.

Symptoms:
Extreme fatigue.
(Especially tender breasts).
Bloating—you may feel like you’ve just had a huge meal when you haven’t.
Solutions:
Hydrate! Dehydration exacerbates fatigue.
Dress for comfort, so wear loose, comfy clothes to make bloating less painful.
Delegate tasks. This is not a time to be too hard on yourself. Let others help you out.

Week 8: The Emotional Rollercoaster

By week eight, your baby is beginning to resemble a little human (albeit tiny — the size of a raspberry). In the meantime, you might feel like a human meltdown. One minute you’re laughing. The next? Weeping at a YouTube video of puppies.

Symptoms:
Mood swings (big time).
You have more nausea and food aversions.
Constipation (yes, it’s a thing).
Solutions:
For mood swings: Find someone you trust to talk to. Sometimes it takes a good vent session to get it out.
For constipation: Increase your fiber intake from food and fluids.
For nausea: Keep trying until you discover something that works: ginger, small snacks or even acupressure wristbands.

Week 9: Tales of The Cravings

Pickles and ice cream? Maybe. Or perhaps you want something completely counterintuitive, such as watermelon in the depths of winter. Cravings tend to set in around week nine, as your baby’s taste buds begin to form.

Symptoms:
Cravings for food (and some REALLY STRONG ONES).
Strange dreams — pregnancy hormones can send your brain into overdrive at night.
More bloating and gas (yes, not glamorous, but true).
Solutions:
Have a little of your cravings, with moderation. It’s all right to treat yourself, but everything in moderation.
For strange dreams: Keep a notebook next to your bed. Writing them down is a good way to process them.
For bloating: Skip carbonated beverages and see if eating more slowly helps to minimize swallowed air.

Week 10: The Glow Begins

By week 10, your baby is officially a fetus (no more “embryo” phase, woohoo!). And guess what? You may begin to see the infamous “pregnancy glow.” Hormones and heightened blood flow make your skin look all glowy and dewy. Of course, not every mom feels glowy — some still feel worn out. Both are normal. 

Symptoms:
Radiant skin (or, for some, pimples).
Continued nausea and fatigue.
Headaches (the hormones again).
Solutions:
Drink plenty of water in order to have your skin its best.
For headaches: Take it easy in a dark, quiet room and keep up with hydration.
For nausea: Don’t skip meals — it can worsen headaches.

Week 11 — Becoming More Like Yourself

Good news! For most moms, nausea and fatigue begin to subside at around week 11. You may not quite feel like yourself. Your baby is growing fast now, about the size of a lime, and their little fingers and toes are fully developed.

Symptoms:
Energy levels may improve.
You may start to see a little bump.
Pain from ligaments as your uterus begins to stretch.
Solutions:
Get that energy high (but not too much!).
Do light exercise, such as walking or prenatal yoga.
For ligament pain: A warm compress or a gentle stretch.

Week 12: Almost There!

You’ve made it to week 12, the final week of the first trimester. Huge milestone! Your baby is about the size of a peach now, and she’s busy growing all the important stuff: her brain, vital organs and more. You may even begin to see some positive changes in yourself!
Symptoms:
Decreased nausea (hurray!).
More energy (for the most part don’t overdo it).
Some women will notice a rounded belly and changes in skin pigmentation (hey there, pregnancy glow!).

Solutions:
Celebrate this milestone! Reflect for a moment on your body and what it’s doing.
If you’re still feeling nauseated, keep those snacks nearby.
Start considering prenatal classes (or resources, etc)—the real journey has begun!

Closing Remarks on the First Trimester

Congratulations, mama! You’ve survived the first trimester — a whirlwind of excitement, struggles and amazing transformations. You can identify the essential vitamins needed to support your health throughout your journey from here. From the excitement of seeing that first positive test to dealing with the highs and lows of early pregnancy, you’ve displayed incredible strength. As you head into the second trimester, many women do begin to feel less nausea and fatigue. This is typically the “honeymoon phase” of your pregnancy, where you can finally begin to enjoy better days ahead. So, the next time you feel discouraged, be proud of how far you’ve come and remember that even if it seems like you’re not getting there, you’re not alone, there is support everywhere, just keep putting one foot in front of the other. You know what to do, take a deep breath and prepare for the next exciting chapters. You have embarked on an adventure, and it is a delightful one!
