What time is she pooping? That is when you take her outside. Make sure you walk around with her...it stimulates her bowels. All of mine are very regular with their poop schedules...I just arranged to be outside then.
As far as urinating...don't wait for her to tell you...take her out on the hour every hour is the best suggestion I can give you.
You also need to be dilegent in removing the odor any where she's gone inside. Nature's miracle works well.
