Hello Respected Sir/ Ma'am My Last Period Date Was July

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
