Belly popped?!

This question is for all you mamas who've had more than one baby . . . Do you remember how far along you were with your second when your belly popped?? Just curious. I'm 8 w 2 d with baby #2 and nothing really yet. I don't have abs and don't really work out so I won't be one of those preggos with a 6 pack at  9 months and a barely there belly. Haha. After I eat I look bigger but really it's not a preggo belly. Also just curious how long I can hide it at work lol. Thanks!!!
