It was awful... It never really happened to me anywhere but Big W. Sometimes woolies... But, i put that down to all the food and morning sickness.
At the beginning of the school year... I was buying socks and undies for my kids... and i was standing at the register... started feeling like i was going to faint... and my DS stood in the line and paid for the items for me while I went and sat down.
Because I wasn't showing a great lot... I must have looked insane!
I think it is the worst when it isn't noticable that you're pregnant... When people can tell, they usually rush to help you
