21 Weeks - Rapid Growth

OK, I could've sworn that I wasn't pregnant until this week. It seems like my belly grew the most it has so far. I think that most people that don't know me would still not know that I'm pregnant. I just look fatter. It is annoying. It would be nice to look definitely pregnant so that I don't feel chubby. I think that I might need to just start wearing my maternity pants. When I try them on, I notice that I do look more pregnant.
