anyone on the Yaz Pill?

Hey girlies! 
So I was due to start my inactive pills this past Saturday all the way up till Tuesday. Would have gotten my period some where then. Instead I delayed my period by four days. So only started taking inactive pills on Wednesday.. Tomorrow is my last inactive pill and I haven't gotten my period yet.. It normally says it should come on day 3.. Yet I am still waiting. I have had unprotected sex. And I have been taking the pill since October 2016.. Just want to know, when am I most likely to get my period? The waiting is killing me!!
