Getting pregnant fears?

Does anyone else question if they will be a good mom or a good mom and wife at the same time?? My husband and I really want a baby and we JUST started TTC a week ago. So many people have told me that kids make things difficult and they change everything, which I know but they are making it seem like a negative change. I'm not really questioning if I want kids or not but rather if I will be a good mom and wife. Help!! 😢
