Brief Answer:
The chances of pregnancy are very less.

Detailed Answer:
Hello dear,

Thanks for trusting us about your health care.
I can understand your concern here.
As you had norethisterone to delay your menses, usually period resume with in a week after stopping the medication but as you had I-pill, now the predictions of mensesis quite difficult.
Now you may have hormonal imbalance due to I- pill, so it may delay your menses.
The chances of pregnancy are less as you had I-pill on time.
So wait for your menses for one to two weeks.
Hope it is useful, feel free to ask more questions.
Good luck.
Regards
