Question: 12 weeks pregnant what does it look like?
Answer: Baby has doubled in size By now your baby weighs a full half-ounce, with a crown-to-rump length of 2 to 2¼ inches: about the size of a lime. It's hard to believe — especially from the outside, since you're probably barely showing at this point — but your baby has more than doubled in size during the past three weeks.
