Your baby continues to grow and develop inside of you. She is now about the size of a large banana, measuring roughly 7 1/2 inches long, and can weigh up to 15 ounces. In the coming weeks, your baby will continue to grow and mature at a fast rate. By week 22, her pancreas, a key player in hormone production, is developing steadily. Her skin may appear wrinkled at this point, but in the coming weeks, she will be gaining enough weight to fill it out.
