My DF & I could see from around 14 weeks from memory. Other people couldn't see anything for quite a while longer.

I remember sitting in Melbourne Pathology with my 5 yo DstepD excitedly talking away to "Brocky" in my tummy while the people seated near me looked at us like she was mad. It was when I had my first GD test so would have been around 24 weeks. It must have looked odd when she was calling him by name and I didn't even appear to be pregnant.

In my third tri I had several people at work completely shocked when they found out I was pregnant. I thought it was completely obvious by then, but perhaps it wasn't.
