Key Milestone Weeks in Pregnancy

In Australia, it is sometimes possible to find out your baby’s sex between 14 and 16 weeks, but it depends on the method and individual circumstances.

• Ultrasound:
  A standard ultrasound may show the baby’s sex from around 16 weeks, but accuracy improves closer to 18–20 weeks, when the anatomy scan is typically done.
• Non-Invasive Prenatal Testing (NIPT):
  This blood test, available from around 10 weeks, can detect chromosomal differences and may reveal the baby’s sex earlier than ultrasound.
• Amniocentesis:
  If performed (usually from week 15 onward), this diagnostic test can also determine sex, though it’s typically done for medical reasons.

Yes, travel and exercise are generally safe at 14–16 weeks pregnant, as long as your pregnancy is uncomplicated and you're feeling well.

Exercise:

• Light to moderate exercise is encouraged and beneficial for both you and your baby.
• Safe activities include walking, swimming, and stationary cycling.
• Exercise can help improve sleep, mood, energy levels, and reduce the risk of complications like gestational diabetes and pre-eclampsia.
• Avoid high-impact activities or those with a risk of falling, overheating, or abdominal trauma.
• Aim for 2½ hours of moderate activity per week, or about 30 minutes most days.

Travel:

• Most women can travel safely during the second trimester, which is often considered the most comfortable time.
• Stay hydrated, move regularly, and wear a seatbelt low across your hips when in a car.
• Check with your doctor or midwife before starting new activities or making travel plans, especially if you have a complex pregnancy or medical conditions.

Between 14 and 16 weeks pregnant, several routine and optional tests or scans may be offered in Australia to monitor your health and your baby’s development:

Maternal Serum Screening (MSS)

• A blood test offered between 14-20 weeks. It’s a screening test, not diagnostic
• Assesses the risk of chromosomal conditions like Down Syndrome and neural tube defects.

Amniocentesis

• May be offered from 15 weeks onward if earlier screening shows increased risk.
• Involves collecting amniotic fluid to test for genetic conditions.
• It’s a diagnostic test, typically recommended in specific cases.

Routine Blood Tests

• May include checks for iron levels, vitamin D, blood group, and infections (e.g. rubella, hepatitis, HIV).
• Often done at the first antenatal visit but may be repeated if needed.

Mental Health Screening

• A questionnaire may be offered to assess emotional wellbeing and screen for anxiety or depression.

Yes, it’s completely normal to still feel tired or unwell at 14–16 weeks pregnant, even though many women begin to feel better during this stage. While the second trimester is often described as the most comfortable and energetic time, some women still experience fatigue or lingering nausea. Your body is working hard to support your growing baby, and hormonal changes, increased blood volume, and physical adjustments can all contribute to feeling tired. If symptoms are persistent or affecting your daily life, it’s always a good idea to check in with your doctor or midwife. They can help rule out other causes like iron deficiency or dehydration.

Yes, you might start to feel your baby move between 14 and 16 weeks, but it’s also completely normal not to feel anything just yet. Women who have been pregnant before may begin to notice gentle movements around 16 weeks. These early sensations are often described as butterflies, flutters, or bubbles. However, if it’s your first pregnancy, you are more likely to feel movement a bit later, typically between 18 and 22 weeks. 

Yes, continuing prenatal vitamins is important throughout your pregnancy. At 14-16 weeks, key nutrients like iron, folic acid, iodine, and vitamin D support your baby’s rapid development and your body’s increased needs. If you’re experiencing side effects like nausea or constipation, talk to your doctor. There may be alternative formulations that are easier to tolerate.

At this stage, it's generally safe to sleep on your back, but as your pregnancy progresses, side sleeping - particularly on your left side - is recommended. Around week 20, the growing uterus can compress major blood vessels when lying flat on your back, potentially affecting blood flow to you and your baby. To get into the habit early, try using a pregnancy pillow to support a comfortable side-sleeping position.
