Is It Normal To Miss A Period The Month After Taking The Contrapill Kit?

Hello Respected Sir/ Ma am My last period date was July 6, 2022, & then we ve did physical relation without protection & on August I ve missed my period, & then for confirmation I ve tested my urine & the results came Positive, but as we were not ready for taking a baby right now, so I ve consumed Contrapill kit on August 16 with suggestions of Gynochologist, & noramally the bleeding has continued 6 days, then stop & no complications, but in this month (September) i didn t get my period on the date, So my question is that, is it normal to let period after taking the pill, if yes so how muny day I ve to wait for ? & Not yes then what to do ?? Please suggest me. Thank you
