As far as I know F2 visa is required only for entering the country and you can stay in US as long as your spouses I-20 is valid. This is the document that is most valid to you. I don't think you need to leave the country. I know a lot of students that have expired F1's. There is no problem as long you don't leave.
Check it with your international student office.
