Welcome to YT! You have come to the right place to get your questions answered. Do you know when your little darlin' "did the deed"? It will be important to know so that you can plan ahead. You will need to have her Xrayed between 50 days and 55 days (that's the range I use anyway, others may have different ideas) so that you will know how many and how big the pups are. I am sure that you will have lots of questions as things progress, so please post them in the Breeder's section to be sure that someone familar with breeding will see your questions and reply.
Again, Congratulations! I know the breeding isn't something you are happy about, but.... it's done and unless there is a serious health risk to mom that would lead to a spay/abortion you are going to be having pups. Start doing some independent research and start looking for prospective moms and dads for the new pups.
