Ask your parents. If they don't know, go to the church where you were baptized and see if they wrote it down.
The baptism will be in the church records where the baptism was done.
You simply write to the Church where the baptism was performed. You give the name of the person baptized, giving the exact name used then. If you have the date, provide it.
