Well, I sincerely hope you are locking her in the spare room for a week. Because she is unclean for 7 days, and if you let her out, someone might accidentally touch her, and they might then also be unclean until evening.
Once she's done her 7 days in the spare room, you need to get down to the pet shop and buy 2 turtles (you can use adolescent pigeons if you really can't get hold of turtles). Take these to your local priest, who will sacrifice them to restore her cleanliness.
"And on the eighth day she shall take unto her two turtles, or two young pigeons, and bring them unto the priest, to the door of the tabernacle of the congregation. And the priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for her before the LORD for the issue of her uncleanness. Leviticus 15:19-30"
