4 Weeks Pregnant – Pregnancy Week by Week

4 Weeks Pregnant – Pregnancy Week by Week

This is game time. If you are pregnant, and had a standard cycle, you will have missed your period at exactly 4 weeks… that means that this is the week you will probably start seeing some of those pregnancy symptoms and you may even get a positive pregnancy test! [Missed your period, but the test is negative? Just wait a couple more days and take another one.]

Your baby is already growing like a weed! Last week baby was the size of a chia seed… this week, they’ve already grown up to a poppy seed! Aren’t you proud?

4 Weeks Pregnant from the Doctor:

Only 4 weeks in, and your baby’s brain and spinal cord have already started to form. Folic acid supplementation, found in most prenatal vitamins, is essential in helping to reduce the risk of spine and brain defects. Starting a prenatal vitamin BEFORE a positive pregnancy test is the best way to help your baby start on a healthy growth track. Ensure your prenatal vitamin has at least 400 micrograms. Some women require more folic acid per day than this dosage, so talk to your doctor about your personal requirements.

4 Weeks Pregnant from the Pregnant Lady:

For me, I was lucky enough to get a positive pregnancy test before technically missing my period on both pregnancies. I found out the first time at exactly 4 weeks to the day, the day of my missed period. This time, I was having such crazy symptoms already – symptoms that I had only ever had during my first  pregnancy – so I took the test and found out two days before my missed period at 3 weeks and 5 days! To me, this is insanity because most people I know have to miss their period and spend that 4th week taking tests like crazy until a line starts to show up! If you’re pregnant, this is the week you’ll know for sure, but the waiting game can be pretty intense.

What are you feeling?

This is the first week that some of the earliest symptoms of pregnancy begin to show up. Don’t feel any of them yet? Don’t worry. Not everyone starts feeling this stuff right away [some don’t feel symptoms at all]. Here are some of the earliest symptoms you may be feeling:

Crazy Boobs

Most women say that their first symptom of pregnancy is tingling, painful boobs. Yes, this is a thing and no, they don’t feel like they do when you get achey boobs right before your period. This pain is more like your boobs are rock-solid painful mountains of doom and any movement – up, down, sideways, a poke from your toddler – will make you cringe. Mine like to flair up in crazy tingles at night while I’m sleeping. In fact, I had one big painful burst that woke me up in the middle of the night about a week before I got a positive test. I thought “OMG does this mean I’m pregnant?” and went back to sleep. Crazy boobs are a thing.


I forgot just how badly I cramped during the first trimester of my last pregnancy, but HOLY COW. The aching. It’s like period cramping, but you’re not on your period and it really never ends! In fact, during my first pregnancy the cramping was so bad that I thought I was starting my period, but then it never came the next morning. Now, I have cramping and aching throughout the day. There’s a direct  correlation between cramping and dehydration so I’m making it mandatory that I sit and rest and drink as much water as possible. I don’t think the Texas Summer is going to help me in this…

Listen up, y’all! Slight cramping is normal, but if your cramping gets really painful or if you also experience bleeding, CALL YOUR DOCTOR IMMEDIATELY. Don’t say “Oh, this blogger says cramping is normal.” Painful cramping accompanied with bleeding is definitely not normal and you need to get to the doctor ASAP. Okay, rant over.


Yup. It’s a thing. I’m so bloated that I swear the baby bump is showing… it’s not. It’s just gas. But that doesn’t stop me from rubbing it as if I’m rubbing a little baby bottom in there. Rubbing my precious little gas baby is making me feel better so don’t judge.


This is also something I forgot about, but I opened up my Ovia Pregnancy app and scrolled AAALLLL the way back to 2014 and found that I logged backaches as a consistent symptom in my early pregnancy last time too. Isn’t motherhood fabulous?

P.S. All of these symptoms are eerily similar to PMS… Have you noticed the trend?


Most women don’t start feeling nauseous this early, which is great. Chances are it’ll start soon. If you’re one of the 10% of women who don’t experience morning sickness, I’m seriously so happy for you! Guess who’s already feeling the gurgles… THIS GIRL. This baby decided it would come with an extra serving of progesterone and mama is FEELING IT. Luckily, I haven’t had to run to the bathroom yet, but let me tell you, I’m nauseous. Big time.

How to Survive this week:

Drink lots of water. Take your prenatal vitamins. If you’re not sick yet, eat some leafy greens. They’re high in folic acid, which your baby needs! Celebrate that positive pregnancy test and celebrate yourself! You’re embarking on an amazing journey and you’ll get to see all the amazing things your body is capable of!

Now is also the time to cut the alcohol out. If you smoke, stop it. If you do crazy illegal drugs, stop those too. Call your OB-Gyn and notify their office and get your first prenatal appointment set up. Make sure to ask about any medications or over the counter medicines you are on and if they’re safe to take while pregnant. Start implementing this rule – WHEN IN DOUBT, CALL YOUR DOCTOR. Don’t go online. Don’t pass go. Don’t collect $200. Don’t assume. Call the doc.
