Week 5 Pregnancy Symptoms

During Week 5, you might start noticing stronger pregnancy symptoms, or if they haven’t shown up yet, they could be on their way. Here are some common signs to watch out for:

  • Nausea: Often referred to as morning sickness, nausea can occur at any time of the day or night, leaving you feeling queasy for hours.
  • Breast Tenderness: Your breasts may become sore, swollen, and sensitive due to hormonal changes preparing your body for breastfeeding.
  • Fatigue: Your body is working overtime to support the early stages of pregnancy, often leading to feelings of extreme tiredness or exhaustion.
  • Mood Swings: Hormonal fluctuations can cause sudden shifts in your emotions, leading to moments of irritability or emotional sensitivity.
  • Pregnancy Brain: The surge in hormones may cause forgetfulness and difficulty concentrating, making it harder to focus on everyday tasks.

Baby’s Growth in the Womb

  • Organ Development: Right now, your baby’s cells are forming three main layers: Ectoderm (brain, nerves and skin), Mesoderm (muscles, bones and heart) and Endoderm (lugs, stomach and other internal organs).
  • Physical Features: Though your baby is still just a cluster of cells, parts of the body are already beginning to form.
  • Weight of the Foetus: At just about 0.1 grams, your baby is still incredibly small, yet growing fast with each new cell division.
  • Movement of the Baby: While it’s too early for movement, the start of the brain and spinal cord is setting the stage for it in the coming weeks.

Your Body in Week 5 of Pregnancy

By Week 5, your body is working hard to support your growing baby, and you may start to feel new symptoms and changes. With hormones like human chorionic gonadotropin (hCG) rising quickly, there’s a good chance you’ve already missed your period.

Physiological Changes During Week 5 of Pregnancy

  • Breast Changes: The rise in hormones can make your breasts feel tender, swollen, or extra sensitive, as your body gets ready for breastfeeding.
  • Skin, Hair, and Nails: Some women find their skin gets oilier or more sensitive. You may notice your hair and nails changing too, as they respond to hormonal shifts.
  • Respiratory and Cardiovascular Systems: Your heart might beat faster as it pumps more blood to support the baby, which can make you feel a bit out of breath sometimes.
  • Uterus and Cervical Position: Your uterus is already growing and thickening to nurture the baby, which can lead to mild cramping or a feeling of fullness in your lower belly.
  • Vaginal Discharge: An increase in cervical mucus is normal in early pregnancy, often with a milky consistency due to the hormone changes.

Medical Scans and Check-Ups

In Week 5, your pregnancy is still in the very early stages, so medical check-ups may not reveal much detail yet. For some, an early scan might be suggested, though it’s often too soon to see much more than a small sac.

  • Blood Tests:

A blood test can confirm your pregnancy by detecting hCG levels. Doctors may also check other hormone levels to ensure your body is supporting the baby’s development. Blood tests at this stage might include checks for anaemia, rubella immunity, and screening for infections like hepatitis B, syphilis, and HIV.

  • Early Scan:

Some doctors recommend an early transvaginal ultrasound if you have a history of complications. This scan can confirm that the embryo has been implanted in the uterus, helping to rule out concerns like an ectopic pregnancy. However, it’s usually too early to see detailed images of the baby.

  • First Doctor’s Visit:

Many women wait until Weeks 8–10 for their first full check-up, but some may opt for an earlier visit to confirm the pregnancy, determine how far along they are, and set an estimated due date. During this visit, your doctor may check your blood pressure, height, and weight, review your medical and family history, and offer advice on nutrition, supplements, and lifestyle for a healthy pregnancy. They may also screen for Down syndrome, assess cervical health, and test for vitamin D deficiency if you’re at risk.
 

FAQs

Why am I feeling more tired?

Your body is adjusting hormone levels to support the embryo, which requires energy. Fatigue is common in early pregnancy, especially with rising progesterone levels.

Is it normal to experience mood swings during pregnancy?

Yes, it’s completely normal to experience mood swings during early pregnancy. Hormonal changes can make you feel more emotional, sensitive, or even more irritable than usual. Many women notice these shifts, especially in the first trimester, and it’s just a part of the process. Don’t worry, these feelings are temporary and will settle as your pregnancy progresses.

Can I exercise in early pregnancy?

Light exercise, like walking, is generally safe, but avoid heavy lifting or high-impact activities until your doctor confirms what’s suitable for you.

What foods are good in Week 5?

Eating nutrient-dense foods is key. Look for iron-rich vegetables, lean proteins, and whole grains, along with plenty of folic acid for neural tube development.

How big is my baby in Week 5?

Your baby is roughly the size of a sesame seed, with critical systems like the neural tube developing quickly.

Is light spotting okay in Week 5?

Spotting can happen in early pregnancy, and it’s often normal. However, you should always contact your healthcare provider to let them know. Spotting is light bleeding that can occur when the embryo attaches to the uterine wall, and it’s common in the first 12 weeks. Still, spotting can also be a sign of miscarriage or an ectopic pregnancy, which can be serious if not treated.

What kind of discharge is normal?

During pregnancy, it’s normal to have more vaginal discharge than usual. It’s usually thin, clear, or milky white, and doesn’t have a bad smell. This is called leukorrhea.

When should I see a doctor if I’m pregnant?

You should see a doctor as soon as you find out you’re pregnant, ideally before you reach 8 weeks. This will help ensure you get the care and advice you need for a healthy pregnancy. By Week 5, your hCG levels are high enough to show up on a home pregnancy test.
