When I was pg with DD, I was at work standing next to my boss (who I hadn't told about my pregnancy yet) when a customer said to me " Ohhh, when are you due??"...... I was 12 weeks!! I am quite skinny though so it is very obvious on me (50kg 161cm). This time around, one of the mum's at school noticed my little pot belly at 5 weeks!!!! There is definately only one in there though but at first i was worried it might be twins! So I am on the other side of the spectrum and was showing early when I wasn't ready to tell the world!!
Hope you pop out soon!!!
