Couldn't find much other than a thread from years ago on one of the anchors that was pregnant in 2000-01, but I found out there was another one in 2012, and both (plus some clips, haven't checked the rest yet) on the Internet Archive.
All clips (non-pregnant, mostly)
Holly Weston clips (see clips from 2000-01 for pregnant)
Katherine Curtis clip (2012), another
