    4 Weeks Pregnant Weird Symptoms And Early Pregnancy Signs

    Jul 6, 2018 · Modified: Feb 5, 2025 by Ali · Leave a Comment

    I’m writing this at 4 weeks and 3 days pregnant. These early days are often the most surreal, filled with excitement, anxiety, and weird symptoms that you might not expect. If you're reading this, you're probably wondering about the early pregnancy signs and what to expect, especially in these crucial weeks of pregnancy. Read on to hear about my 4 week pregnant symptoms and pregnancy signs week 4.

    Early Signs of Pregnancy

    At 4 weeks, your body is starting to undergo significant changes as pregnancy hormones, specifically human chorionic gonadotropin (hCG), start rising. This hormone is what’s detected in home pregnancy tests, giving you that exciting positive pregnancy test result. The fertilized egg has implanted into the uterine wall, and the embryo is now about the size of a poppy seed.

    Missed Period and Implantation Bleeding

    The first major symptom that usually tips women off is a missed period. But even before that, some women experience implantation bleeding, a light spotting that occurs when the fertilized egg implants into the uterine wall. I didn’t have this myself, but many women report this as one of the first signs.

    Weird Symptoms at 4 Weeks Pregnant

    During these early stages, you may notice unusual symptoms that could catch you off guard. These symptoms are the result of the rapid hormonal changes happening in your body as it starts supporting the growing baby.

    Stomach Cramps and Abdominal Pain

    I’ve had abdominal cramps in every pregnancy, and this time was no different. These cramps can feel similar to period pains, which is why many women mistake them for the start of their monthly period. Cramps can be a common early pregnancy symptom, but they can also cause anxiety, especially if you've experienced a pregnancy loss in the past.

    Breast Tenderness and Soreness

    Tender breasts were one of my first clues that I might be pregnant. Hormonal changes cause an increase in blood flow to your breasts, making them feel sore or swollen, a common early sign.

    Heightened Sense of Smell and Food Aversions

    One of the more bizarre symptoms I noticed was a heightened sense of smell. Certain foods suddenly became repulsive, triggering nausea. This was closely followed by food cravings, a common symptom that many women experience.

    Metallic Taste in Mouth

    Another strange symptom at this stage is the metallic taste in the mouth, sometimes referred to as "pregnancy mouth." This is a result of hormonal fluctuations, specifically an increase in estrogen.

    First Trimester Symptoms

    The first trimester brings an array of early pregnancy symptoms. In addition to the missed period and tender breasts, you may also start experiencing morning sickness, although it can happen at any time of day. Thankfully, I haven’t had too much of it yet, just mild nausea when I’m hungry. Some women, however, suffer from severe morning sickness or even hyperemesis gravidarum, which may require medical attention.

    The Importance of Prenatal Care

    At 4 weeks, you may not have had your first prenatal appointment yet, but it’s important to schedule one as soon as you know you're pregnant. Your healthcare provider will likely recommend starting prenatal vitamins, including folic acid, which helps prevent neural tube defects in the growing baby. Regular prenatal care is key to ensuring a healthy pregnancy and monitoring baby development and catching any potential medical conditions early.

    Thyroid Concerns and Hormonal Imbalances

    Because I have subclinical hypothyroidism, I knew I needed to get my blood tests done early. Pregnancy can exacerbate thyroid issues, and managing your hormone levels is crucial for both your health and the baby’s development.

    Coping with Anxiety and Fear

    Having lost a pregnancy before, these early weeks can be an emotional rollercoaster. It’s natural to feel scared and anxious. The thought of miscarriage can be overwhelming, especially with symptoms like stomach cramps. But staying positive and focusing on a healthy pregnancy routine can help alleviate some of these fears.

    Maintaining a Healthy Lifestyle

    Staying active during pregnancy is important for both your physical and mental health. I’ve kept up with my power walking, yoga, and light kettlebell exercises, though I’ve been gentler on myself. It’s also essential to eat smaller, balanced meals with whole grains, fruits, and vegetables, ensuring you’re getting enough vitamin C and other nutrients to support the pregnancy.

    Changes in Your Body

    As your body adapts to pregnancy, you may start noticing other changes, like increased vaginal discharge or urinary frequency. These are all common symptoms of pregnancy caused by the increased blood flow and hormonal changes.

    Weight Gain and Baby Bump

    While it’s still early for most women to notice a baby bump, the body begins to prepare by expanding blood vessels and increasing blood volume. This can sometimes lead to varicose veins or visible changes around the belly button. Every pregnancy is different, and how soon you show can depend on various factors.

    What to Watch Out For

    While most symptoms are normal, there are some signs that may require medical attention. Ectopic pregnancy, for example, is a serious condition where the fertilized egg implants outside the uterus, often in the fallopian tube. Symptoms can include severe abdominal pain, light spotting, or vaginal bleeding. If you experience any concerning symptoms, it's important to seek expert advice from your healthcare provider.

    Good Oral Hygiene and Pregnancy Health

    One symptom often overlooked in early pregnancy is the effect on your oral health. Pregnancy hormones can increase the risk of gum disease, so it’s a good idea to practice good oral hygiene throughout your pregnancy.

    Navigating the Emotional Journey

    The first few weeks of pregnancy can be mentally exhausting. You may have vivid dreams, mood swings, and feel a sense of disbelief. It’s essential to lean on your support system and stay connected with your healthcare provider for advice and reassurance during this exciting but sometimes challenging time.

    Conclusion: Embracing the Pregnancy Journey

    At 4 weeks pregnant, your baby is still the size of a poppy seed, but a lot is happening inside your body. From early signs like tender breasts to the more unusual symptoms like a metallic taste or heightened sense of smell, each pregnancy is unique. The journey is just beginning, and taking care of yourself with proper prenatal care and a healthy lifestyle will set you up for a healthy pregnancy.

    Whether you're experiencing weird symptoms or the more common ones, the first trimester can be full of surprises. But with the right support and knowledge, you can navigate this exciting time with confidence.
