Am 6+3 with #3.
I'm slim (size 6-8) and had got a fairly flat stomach back after #2 prior to getting pregnant. When I do up my dressing gown now (thin material, not the bulky sort) I definitely seem to already stick out a little below the belt. I'm not sure though if that's just a lack of exercise: I normally work out lots and hard but haven't been able to manage anything even vaguely resembling what I class as a 'workout' since 4wks....
I'm due to go to a wedding in a few weeks when I'll be 9wks or so. I really really do not want people to know for loads of reason (thunder stealing, friend who recently lost a baby very traumatically etc etc).
Obviously none of you can tell me for sure, but based on experiences with babies 3 plus am I likely to have a proper baby bump by then? Should I plan a disguising sort of dress accordingly? If it's of relevance I wasn't showing by 12wks with #2 (well I thought I was but nobody guessed until 14wks apparently).
