Content: Week 11 and Beyond
Congratulations, you’ve graduated from having an embryo to a fetus. From week 11 onward, your baby will continue to develop and grow until the end of your pregnancy. Here’s more of what they’re up to. Late First Trimester
Your baby’s development is still in high gear for the rest of the first trimester. They’ve even started to grow fingernails. Their face has taken on more human characteristics. By the end of week 12, your baby will be 2 1/2 inches from crown to rump, and weigh around 1/2 ounce. Second Trimester
Week 13 marks the start of the second trimester. During this stage, your fetus is looking and operating more like a real baby. Early on, their sex organs are developing, their bones are getting stronger, and fat is starting to accumulate on their body.
