Your baby is the size of a Blueberry. Discover exactly what is happening to your body and your baby this week.
Week 7 in detail
The brain is adding neurons at a very high rate. Nostrils, lens pits, and hand plates are appearing. Kidneys are getting ready to make urine later. A tail is still there; it will recede. Skip viral “X neurons per minute” figures — the point is speed, not a lab count.
The uterus has grown a lot from its non-pregnant size, which can mean pelvic ache or more toilet trips. Blood volume is starting to rise. Rest is a medical need this week, not laziness.
Protect sleep like an appointment. The checklist above is rest, carbs, and water. If you cannot keep fluids down for a day, call — hyperemesis is a diagnosis, not a badge.
A general guide, not medical advice. Scan timing and symptoms vary — ask your clinician.
