My friend had a frozen embryo transfer after not getting pregnant with IVF and has twin girls. Like pp said it really depends on the grade of the embryos after the thaw of how many they would put back. I would think you would have to endure all the testing again (maybe not as extensive) since your body can change so much especially after having a baby. You still have to do the medications but I don't think they are as much. Let me email my friend and ask her the specifics and then post again.
