7 Weeks pregnant - What to expect ?

Những thay đổi của thai nhi tuần thứ 7

When you are 7 weeks pregnant, you are just over halfway through your first trimester. Even if you don’t look pregnant or feel your best, your body is working intensely to support your baby’s growth. At this stage, it’s common to compare your baby’s size to fruits because it’s easier to visualize—your little one is now about the size of a corn kernel, raspberry, grape, small bean, or blueberry.

Your uterus is about the size of a medium orange, and your baby has grown nearly 10,000 times larger since conception—though you still won’t feel movement until the second trimester.

Your physical changes this week

Common pregnancy symptoms at 7 weeks include:


Digestive Symptoms

  • Constipation due to progesterone slowing down bowel movement
  • Nausea, vomiting, food intolerances
  • Heartburn
  • You could be feeling a second bout of adolescence with an outbreak of pimples. This is purely due to the influence of hormones racing around your body.

Oral & Sensory Changes

  • Excess salivation causing frequent swallowing
  • Heightened gag reflex when brushing your teeth

Skin & Body Temperature

  • Hormonal acne or pimples
  • Sensitivity to heat from increased blood volume
  • Feeling thicker around the waist (even though the uterus is still low in the pelvis)

Energy Levels

  • Fatigue that doesn’t improve with sleep—very common in early pregnancy

Your emotional changes this week

  • Continued disbelief about being pregnant
  • Possible guilt if friends are struggling to conceive
  • Realization of pregnancy may feel overwhelming
  • Talking to your mother or other moms can help normalize these feelings

FAQ: 7 Weeks Pregnant

At 7 weeks pregnant, your baby is developing rapidly—facial features, limb buds, brain cells, and early organs form—while you experience common early pregnancy symptoms like nausea, fatigue, and constipation.

Your baby is about the size of a raspberry, or roughly a small bean/blueberry. Your uterus is about the size of a medium orange

Yes, nausea is very normal due to hormonal changes. It may last most of the day and is often accompanied by food aversions.

No, constipation is common at this stage. Progesterone slows bowel movement. Drinking water and eating more fiber can help.

This happens because increased saliva production is common in early pregnancy. It’s harmless but may feel uncomfortable.

Your body feels hotter due to increased blood volume and hormonal surges typical in the first trimester.

Your baby is forming bones, facial features, mouth, tongue, and limb buds. Brain cells grow at rapid speed—around 100 per minute.
