Hi, I've just been for my 12 week scan today and the technician revised my due date to make me 11 weeks and a day. She measured baby at 12cm, is this normal for 11 weeks? I've looked online and everywhere said that baby should be only about 4-6cm. Who's right? I know the technician knows what she's talking about, but based on what I've read about size that's how big online says a 15 week baby should be. Or do I just have a large baby growing inside? I know it's a silly question really but I was just curious if anyone knew. Thanks.
