> This week often brings the exciting milestone of a detectable heartbeat, as your little one, now the size of a sweet pea, continues its rapid, intricate development.

Welcome to week 6! This early stage of pregnancy can be a fascinating blend of profound internal changes and external quiet. While your body is working diligently behind the scenes, you might be feeling a mix of emotions, often amplified by the physical shifts happening.

## What's happening with baby

At six weeks, your baby is roughly the size of a sweet pea, measuring about 5mm. This is a week of incredible foundational development. The most significant milestone for many parents is the first detectable heartbeat, which can often be seen on an early ultrasound. This tiny flicker is a powerful reminder of the life growing within you. Beyond the heartbeat, the neural tube, which will become the brain and spinal cord, is closing. Early facial features like the eyes, ears, and nose are beginning to form, and tiny limb buds are appearing, which will eventually develop into arms and legs. It's a period of rapid cellular differentiation, laying the groundwork for all major organ systems.

## What you might be feeling

For many, week 6 is when early pregnancy symptoms really start to make their presence known. Nausea, often called 'morning sickness' but capable of striking at any time, might be intensifying. You could also be experiencing significant fatigue, as your body dedicates immense energy to supporting this new life. Breast tenderness and swelling are common, along with more frequent urges to urinate. Emotionally, you might find yourself on a rollercoaster – from immense joy and excitement to anxiety, overwhelm, or even a sense of disbelief. All of these feelings are valid and a natural part of this unique experience.

## A doula's lived take

From my perspective as a birth doula, this early phase, often called the 'invisible' pregnancy, is a time of profound internal processing. It's common to feel a sense of quiet anticipation, perhaps even a bit isolated, as the news might still be very private. Remember, your body is doing something truly remarkable, and it's okay to feel tired, queasy, or emotionally sensitive. One option might be to start a simple journal to track your feelings and any questions that arise. This can be a gentle way to process what's happening and prepare for conversations with your care provider. Prioritizing rest and gentle hydration can make a big difference in managing early symptoms. You get to decide how you navigate these early weeks, making choices that feel supportive and right for you.

## Questions worth asking your provider

As you move through these early weeks, it's helpful to feel clear and confident about your care. Some questions you might consider asking your OB or midwife this week could include: What early screening options are available, and what do they involve? What are some evidence-based approaches for managing nausea or fatigue that you recommend? What can I expect at my first prenatal appointment, and when will that typically be scheduled? Your provider is your best resource for personalized guidance and medical advice tailored to your specific situation.
