Bilingualism would not be my first thought, as it usually does not impact language growth.
It's great your daughter can use some words and express the way she feels. That shows that she understands the purpose of language.
Typically many 3 yr old children are able to express themselves in connected sentences, making comments, asking questions and answering questions in some detail.
If you are concerned about your daughter's development, or even just curious why she is developing in the style she is, your local school system should offer free screening from the age of 3 and older. In addition to the screening, it's always a good idea to have her pediatrician schedule a hearing test, as even a small hearing issue can greatly interfere with language acquisition.
