It depends what country you are from. Use this chart online to determine the wait taimes: http://www.travel.state.gov/visa/bulletin/bulletin_5630.html . It is the Visa Bulletin issued by the Department of State. F-2A is the category but each country has different wait times... Good luck.
You haven't given us sufficient information to guide you. We'd need to know when you filed the I-130 and your country of origin. This would give us a better set of facts with which to work.
