When should my period start??

I ovulated late as i had

IUI

done this month and my doc was monitoring my cycle to see when I ovulated so I could go in for my

IUI

.. I ovulated on the 25th of last month..im just wondering when should my period start bcuz my period is usually every 30-32 days according to glow im late but according to my doc she said i should wait up a week to test ... i did test today 12dpiui and it was a bfn :( am i too early? I have symptoms: fatigue..sore breast and they feel heavy..left ovary twinges and mild cramps on and off... jw if im out or not i know i should wait a week but i think thats too long for my period to start bcuz every month it starts after 30-32 days
