I cannot answer your post with 100% certainty as I do not know a lot about Mollies at all, however from looks alone, yes she looks pregnant.
I would suggest if she has given birth, either leave the fry alone or if you want to remove them, search in and around decorations (the fry will want to stay as hidden as possible)...this will likely lead to stress of the other fish and may expose your fry.
I may suggest a breeder net or box if you are worried the fry may be eaten by your other fish.
Something like
