Okay so just had my 28 week check up. Karleigh's heartbeat was 152 so steady and strong. The doctor said I was measuring 30. Does that mean that I am measuring 30 weeks? With my first pregnancy, our doctor never told me what I was measuring or anything. so I'm just curious if that's what it means! I feel huge so I guess I wouldn't be surprised if I was measuring 2 weeks ahead
