Your Baby This Week

Big News! Your baby is now officially a fetus. They are about 41mm long and starting to explore a bit like opening their fists, but it's too soon to feel any kicks. Their external genitals are starting to form this week, though it's too early to determine the sex via ultrasound.

Your Body This Week

As you near the second trimester, your morning sickness may be easing and your appetite may be gearing up. You might feel aches in your belly as ligaments stretch. The placenta is taking over to nourish the baby, a hormonal shift that might leave you feeling tired and emotional.
