Brief Answer:
Wait for your menses one week.

Detailed Answer:
Hi,

Thanks for the query.

I can understand your concern here.

The chances of pregnancy are very low in your case as you had sex in your safe days and took I- pill within time but nothing is 100%.

So you should wait for one more week, if you will not resume your period after it, repeat a home urine pregnancy test.

If test results are negative, wait for your menses or you can take medication for withdrawal bleeding after consulting your Gynecologist.

Period may be delayed due to side effect of I-pill.

Hope it is useful, feel free to ask more questions.

Doctor

Can you not prescribe a medicine for withdrawl bleeding which i can have only after a week when tests are Negative .

I had two ipills during the period , would that cause more delay than the usually a single could .

Brief Answer:
You can take pills under doctor consultation.

Detailed Answer:
Hi,

Sorry for delay in my response.

You can take progesterone for withdrawal bleeding after consulting your treating doctor because it is a prescription medicine.

Yes, if you take two pills in one cycle, it will further delay your period.

Hope it is useful.
