Ivf question

My husband and I have been trying for 4 years. No none fertility issues but we have 5 failed IUI's and we just found out 2 weeks ago our first round of ivf was a fail I stopped the progesterone when they said I wasn't pregnant but I have still yet  to get my period. I called my doctor they said if I don't get it by Monday come it. So my question is how soon after you stopped the progesterone after a failed ivf did you get your period and should I be worried?
