How does birthright work, and will i have to convert?

[Chavak]

I'm a little confused by your posts, but it sounds like your father was Jewish and your mother was not. You were not raised Jewish. My understanding is that you would not be considered to be a Jew by any sect of Judaism. You would need to convert. If you wish to convert Reform, you need to contact a Reform rabbi. Rabbi O here should be a good source to get you started.
