Pregnant for 4 Weeks

Pregnancy symptoms may appear at 4 weeks, as the baby is transitioning from a blastocyst to an embryo.

At 4 weeks, how big is your baby?

This week, your baby is less than 0.05 inch long. That is about the size of a poppy seed.

4 Weeks of Your Baby’s Development

If you looked at your baby on an ultrasound at 4 weeks, you wouldn’t notice much, but there is a lot going on at this point of your kid’s development. The fertilized egg has been implanted in your uterus and is rapidly growing.

The blastocyst (essentially a collection of cells) is separating this week, eventually transforming into your placenta (a whole new organ) and an embryo (hello, baby!).

Preparing for growth: The gestational sac, although being a small dot that can barely be seen on an ultrasound, contains blueprints for your baby’s nose, toes, and pretty much everything else concealed in their chromosomes.

Top Pregnancy Tip for 4 Weeks Pregnant

If you aren’t already taking one, incorporate a prenatal vitamin with 600 mcg of folic acid into your daily regimen. Folic acid helps to prevent birth abnormalities and may even help to decrease your child’s blood pressure as they develop.

Your Body: Pregnancy Symptoms at 4 Weeks

PMS symptoms vs. pregnancy symptoms: Many women find it difficult to distinguish pregnant symptoms from usual PMS symptoms in the early stages. After all, PMS symptoms include moodiness, exhaustion, aching breasts, bloating, and constipation. However,

  • PMS eventually leads to menstruation and then disappears. Pregnancy symptoms normally last during the first trimester. Unsure? The only way to tell for sure if you’re pregnant is to take a pregnancy test.
  • Missed period: You may not feel pregnant yet because it is so early, but wait? Aunt Flo, where are you? Missing your period may be the first indicator of pregnancy and the impetus for you to take a pregnancy test.
  • Pregnancy test results: Some at-home pregnancy tests are reliable at this time, but it might be a few days or even a week before you have enough hCG (a pregnancy hormone) in your urine to detect with an at-home test. If the at-home test was negative, you may arrange a blood test (which is extremely sensitive) in your doctor’s office or lab, or you could test again a few days later with a different pee stick. If the at-home test came back positive, you can be quite certain you’re pregnant.
  • What do many women sense before nausea, vomiting, and acute fatigue? Sore breasts. Boobs that are sore or swollen. It’s difficult to think that your body is already preparing to feed a kid at 4 weeks, but it is.
  • Fatigue: As your pregnancy hormones spike and your body begins to generate more blood to sustain your kid, you’re sure to feel fatigued. In fact, you may be completely fatigued.
  • Spotting: Because implantation bleeding occurs in around 30% of women when the embryo adheres to the uterine wall, don’t be shocked if you have some mild spotting. Bleeding is usually a different hue than a period, such as pale pink or dark brown.
  • Light cramps: Implantation cramps exist as well. These little pains should only last a day or two.
  • Have you seen any signs yet? You’re not by yourself. However, during the first trimester, hormones spike and your body works hard to begin the process of producing a baby.
  • In the next weeks, you may notice the following symptoms
  • Nausea and vomiting: Approximately half of the pregnant women have morning sickness (which should actually be considered all-day sickness); it generally begins around week 6 and subsides around week 12.
  • Aversions to certain foods: What is the cause of nausea? Having an aversion to foods you used to enjoy. You could find yourself drastically altering your dietary habits.
  • Urge to pee frequently: Around 6 to 8 weeks, hormonal changes along with increased blood flow lead the kidneys to produce more urine than usual, so you may be going to the toilet frequently.
  • Constipation: Your intestines may slow down, and the iron in prenatal supplements may cause you to get constipated. Consume plenty of fiber and water, and try to maintain a healthy level of physical activity. Walking is your best buddy!
  • Mood swings: You’re fatigued, your metabolism is changing, you may be anxious, and your hormones are all over the place right now. It’s no surprise you sobbed when you saw the Oreo commercial.

While these are all normal pregnancy symptoms, keep in mind that some pregnant women may not experience any first trimester symptoms at all. The absence of symptoms does not imply that something is wrong; rather, each pregnancy is unique.

Your Life When You’re 4 Weeks Pregnant

Your body will be hard at work for the next nine months creating a new tiny individual. But it’s also crucial to remember that you’re still a person and to set aside some time for yourself. Here are some suggestions.

  • Top tip: Give yourself (and your partner, if you have one) time to comprehend this big milestone. You’ve just learned some life-changing knowledge! You may not be ready to share your news just yet, but if you want to, take some time to dwell on your emotions. Write it down in a notebook or in a letter to your future self, or discuss it with a partner or a friend on a long walk or over a quiet supper at home.
  • Have some fun: Speaking of sentiments, your imagination may begin to work overtime imagining the following nine months, much alone how things will be after your kid comes. It’s still early, so if you feel yourself getting ahead of yourself, settle down with a baby-free series on Netflix. To keep oneself entertained, watch Schitt’s Creek or Broad City.
  • Prepare yourself: Whether you’re excited, frightened, or somewhere in the middle, consider preparing for what’s to come by reading these new-school baby books for a modern approach to pregnancy and parenthood. Expecting Better and Raising Bebe are both terrific places to start.
  • Consume: According to the American Pregnancy Association, more than half of pregnant women will suffer from morning sickness at some time throughout their pregnancy. The good news is… It normally takes a few weeks for things to get going. In the interim, treat yourself to a meal at one of your favorite restaurants to commemorate your hunger.

Checklist for 4 Weeks Pregnant

  • Perform four more at-home pregnancy tests. I’m joking! One is sufficient.
  • Make an appointment with your OB/GYN for your first prenatal visit, which will most likely take place around week 8.
  • Take a big breath, whether you’ve been trying for months or this is a surprise. Everything will change as a result of this, but that’s the goal.
