TRIMESTER 1 · WEEK 6
What to expect at 6 weeks pregnant: your baby, your symptoms and this week’s reminders.
Small buds that will become arms and legs appear. Structures in the head and body begin taking shape.
Early cardiac activity may be visible on some transvaginal ultrasound scans. Timing varies with individual development and the accuracy of pregnancy dating.
None of these symptoms is required. Symptoms alone cannot diagnose pregnancy or establish your baby’s wellbeing.
Seek medical assessment if vomiting prevents you from keeping fluids down.
