Announcement Of Pregnancy

Just to know if mommies(to-be) out there experience the same? #1 and bump is not showing yet at this time. Prefer not to announce until bump is obvious. But this poses frustrations sometimes like feeling that no one takes care/concern/understanding towards me (unlike how we would treat others who are pregnant) eg. Family making comments about fussy eating when needed to avoid certain 'unsafe' food, colleagues/friends making nasty/unnecessary comments which you won't say to an expecting woman. Felt upset at times. What's your experience?
