cat by door

we found a stray and have been feeding her for about 2 weeks now. she comes back of course but we think she’s pregnant as she looks like it but not sure. after she eats she still sits by the door and meows and she puts up her paws by the screen door to peak inside the house. we don’t know what else she could possibly want? not sure what my mom wants to do with her but she has a puppy as well that’s an in home dog a little pomerarian. but we are just trying to figure out why she always stands at the door and meows all day? anyone have a clue? we aren’t a cat family so idk
