12 weeks pregnant: Fast facts
Your baby is about the size of a lime – a little more than 2 inches from head to bottom – and weighs 1/2 oz.
Your baby has reflexes! Fingers open and close, toes curl, eye muscles clench, and your baby's mouth makes sucking movements.
You're more vulnerable now to bacteria and parasites in food. Skip raw or undercooked meat and eggs, unpasteurized cheese or milk, deli meats (unless heated to steaming hot), and high-mercury fish.
Your breasts may feel swollen, sore, tingly, and sensitive, thanks to pregnancy hormones. And don't be surprised if they grow a size or two!
If your employer doesn't offer paid maternity leave, you have other options. Lots of women use a combo of short-term disability, paid time off, and unpaid family leave.
