in the wedding episode, could anyone else tell that dana plato was pregnant? She wore two really baggy outfits and kept her bouquet in front of her stomach. Am I the only one who noticed?

Yes, it was especially noticeable during the side shot of Kimberly hugging Mrs. G.

i could tell too.
that's actually the reason why she was'nt on the next season. they fired her because she was pregnant. at least they brought her back in the final season.

Yes. It was kind of obvious.
