I agree with her ☝. Every pregnancy is different. Try not to worry so much that your belly isn't as big as the woman you work with. To make your baby kick try a glass of organge juice or at my OB they gave me a lollipop and apple juice to get my daughter to kick when I was pregnant. If it doesn't help and your still worried go in. It's always better to get checked or call your OB if you have any doubts.
