Development

What is developing around week 23

Around the 20-week source checkpoint, activity increases; hearing and swallowing are developing, and some pregnant people begin noticing movement, although timing varies.

Your body

Changes you may notice

Second-trimester changes may include a growing abdomen, back or pelvic discomfort, skin changes, tingling hands, and swelling. Sudden or extreme swelling, significant itching with other symptoms, or anything that feels wrong deserves prompt clinical guidance.

Symptoms vary widely. Absence, presence, or intensity of a symptom cannot confirm that a pregnancy is progressing normally.
