joan,
usually lucrin for 14 days then blood test and scan to check on the suppression, if it is okay, you can start your puregon for usually 14 days too, in between you will go back for scans to monitor the growth of the follicles and final injection of pregnly to release the eggs for Egg Retrieval and 2 days later to transfer the embryos, lucrin is not expensive, puregon more expensive and depends on the dosage, by now, your dr or nurses shd have already briefed you on the charges right?, during this IVF, you are to do safe sex, other than that, you can continue your normal activities, only rest after embryos transfer.
