urine pregnancy test advised

Detailed Answer:
Hello dear, I understand your health concerns.
First do a urine pregnancy test and see for results.
In case positive then just let me know, but in case negative there is nothing to worry about it and just wait for periods.

Brief Answer:
still do a pregnancy test

Detailed Answer:
Yes ipill can result in delayed periods so its best to test for pregnancy and if ruled out then just wait for periods and that's all.
Get a pregnancy test kit and put 2-3 drops of morning first void urine of your partner and see for two lines in case only single line appears then its a negative result.
All the best

Good to hear that your pregnancy test came out negative.
Give her tablet norethisterone 5 mg thrice a day for 3 days and then she will get periods in 2-7 days.

Brief Answer:
can wait for another week

Detailed Answer:
In case you have not had any sexual activity after that then there is no risk of pregnancy as the test is negative.
You can wait for another week for spontaneous periods without any risk.
These tablets have no major long term side effects so nothing to worry and you can take them after a week of wait.
Periods can be delayed for any amount of time and even till 2-3 months so nothing to worry.
All the best
