Pregnancy Week by Week

Congratulations mama! Your body is doing tremendous work right now as your little one continues to develop in the weeks to come. At 5 weeks, you may be feeling a mixture of excitement and apprehension over what’s ahead for both you and your baby. After all, this is a time of many changes!

That being said, it’s important to remember that no two pregnancies are alike — and even if you’ve been through this before, your experience may be unique. As always, it’s best to talk to a healthcare provider about any questions or concerns that come up.

The 5 Weeks Pregnancy Digest

Here are some of the most common changes and expectations for you during week 5 of your pregnancy:

  • Your baby’s development: Your baby is now about the size of a sesame seed and has begun to form all its major organs, like the heart and lungs.
  • Symptoms you may be experiencing: You may experience increased fatigue due to hormonal shifts. Nausea, bloating, and increased need to pee are other common symptoms to expect at 5 weeks pregnant. If your breasts are feeling tender, it could be a sign that your body is preparing for breastfeeding. A pregnancy test might register positive by now!
  • Tips and Tricks: To help increase your energy, make sure to get plenty of rest and drink lots of water. Eating small, frequent meals can also help keep up your energy levels.
  • Keep an Eye Out For: While it’s normal to feel some anxiety during pregnancy if you find yourself feeling overwhelmed or unable to process your emotions, reach out to a professional for help.

Remember, you’re in the midst of an incredible transformation — and that’s worth celebrating! Enjoy this special moment and savor the journey ahead. You’ve got this mama!

Week 5 for Your Baby

The little ball of cells that is slowly becoming your baby is growing by the minute. It will measure between 2 and 3 millimeters (0.08 to 0.12 inches) at 5 weeks.

Your Baby Is as Big as …

a sesame seed! This week marks an exciting milestone in your little one’s development — all major organs are beginning to form, including the heart and lungs. At this stage, your baby is just a tiny dot with no recognizable features, but it already has all it takes to become a beautiful baby!

Major Developments for Your Baby This Week

At 5 weeks, the beginnings of your baby’s cardiovascular system are taking shape. Blood vessels are appearing. About 7 days after fertilization, a little tube-shaped heart is formed, and it will start to beat shortly.

Three separate layers of cells are laid down. These are the building blocks that will eventually become your baby’s organs and bones. In the next few weeks, these layers will form muscles, intestines, and other vital organs. Here is how:

  • The outer layer called the ectoderm, forms the neural tube that will develop into your baby’s nervous system. Skin, hair, and nails will also develop from this outer layer!
  • The middle layer, the mesoderm, forms the major structural tissues of the body including the bones, muscles, and organs like the heart.
  • The inner layer, called the endoderm, will develop into your baby’s digestive system. Lungs, intestines, the pancreas, and the thyroid gland will all form from this layer.

The early placenta starts to develop this week too. It will offer your baby a safe haven and provide all the nutrients, oxygen, and hormones they need to grow. Although, at this stage, nourishment still comes from the yolk sac.

Your Body at 5 Weeks Pregnant: Common Symptoms

At 5 weeks pregnant, your body is undergoing changes in order to accommodate the new life growing inside you. You may start to experience nausea and breast tenderness. An increased need to use the bathroom is also common.

Your hormones are in full swing, so fatigue and mood swings may become more prominent. You may even start to experience cravings and food aversions. Remember that it’s normal for your body to go through changes during this time, but if anything feels off, be sure to contact a healthcare provider right away.

A Positive Pregnancy Test?

By 5 weeks, over-the-counter pregnancy tests may start to pick up the faint traces of the pregnancy hormone hCG in your urine. If you do get a positive result, it’s important to follow up with a medical provider so they can confirm that all is progressing normally and answer any questions you may have.

Taking Care of You at 5 Weeks Pregnant

It is important that you take good care of yourself during this time as your body is going through many changes. Here are some tips for self-care:

  • Get plenty of rest – this will help your body adjust to the new changes.
  • Drink lots of fluids – staying hydrated is key for a healthy pregnancy.
  • Eat small, frequent meals throughout the day – this will keep your energy levels up and help stave off nausea.
  • Talk to friends and family – don’t be afraid to lean on your support system. Whether you need a shoulder to cry on or just want someone to listen, they can be there for you.

At 5 weeks pregnant, it is crucial that you prioritize self-care! Taking the time to nurture yourself and your growing baby can make all the difference.

Prenatal Checklist: What to Do This Week?

Getting a positive pregnancy test can be both exciting and overwhelming. Here’s a checklist to help you stay organized:

  • Schedule your first prenatal appointment – this is when the doctor will confirm that you are pregnant and discuss any questions or concerns you may have.
  • Book your first ultrasound appointment using your ultrasound requisition. This ultrasound is done around 8 weeks of pregnancy and is done to confirm dating and viability.
  • Talk to your partner about parenting plans – it’s never too early to start talking about your expectations and responsibilities.
  • Start taking a prenatal vitamin – to ensure your baby gets the proper nutrients they need for development.
  • On top of your prenatal vitamins, remember to eat a balanced, healthy diet – focus on nutrient-dense foods that will give you the energy and essential vitamins and minerals that you need.
  • Join an online pregnancy group – connect with other parents-to-be who can relate to your journey.
  • Get the right amount of exercise – regular exercise is important for pregnant women and helps keep you and baby healthy. Remember to start slow and get clearance from your doctor before getting started!
