Brief Answer:
need to consider pregnancy test

Detailed Answer:
HI, thanks for using healthcare magic


Postinor 2 is an effective form of emergency contraception. It can prevent 85% of expected pregnancies like most emergency methods.

Though this protection is not as high as the regular use of normal oral contraception which offers up to 99% protection, it is still high.

The postinor would have helped to prevent any pregnancy that would have resulted from intercourse on the 30th of may because it was taken correctly but would not have any effect if she is already pregnant from previous intimacy.

Since her period was due on the 28th of may and has not occurred. She may need to consider a pregnancy test to rule this out.

Pregnancy tests can detect pregnancy from day 11 to 14 of conception.A blood test can detect it slightly earlier. They detect the level of the HCG hormone.

If this test is negative then she may consider other causes of period delay such as: (1)emotional stress or illness
(2)physical illness
(3)thyroid disease
(4)high levels of prolactin hormone
(5)inadequate diet
(6)extreme physical activity
(7)polycystic ovarian syndrome
(8)idiopathic-cause not known

Summary: Postinor would be helpful for the may 30th intercourse (if not already pregnant) but would not affect if already pregnant.
Needs to do pregnancy test, if negative consider other options

I hope this helps, feel free to ask any other questions

Brief Answer:
not likely pregnant, test tomorrow will confirm

Detailed Answer:
Hi

Yes, the result should be accurate at 13 days. If the test tomorrow is also negative then it is she is not likely pregnant and one of the other causes mentioned may be causing her period delay.

She can just wait it out if she is comfortable with that, that would be fine.

Some women ask there doctor for medication to induce the period. If she prefers this, she can visit her doctor for a prescription.

Please feel free to ask anything else

Brief Answer:
different options available to you

Detailed Answer:
HI

It is understandable to be concerned. She can consider waiting for another week to see if it comes or going to her doctor now who can give her medication to help induce her period (doctor would likely also repeat pregnancy test at office for the medical records).
Either of these options is fine

IF this period delay recurs in the future she may want to consider visiting her doctor for some blood tests to rule out the other causes of delayed period .

These include:thyroid hormone , prolactin, testing for polycystic ovarian syndrome

These are the more common organic causes of delay.

As mentioned any emotional or physical illness or stress can also have an effect on the period.

It is probably best to see her doc for an examination and the tests mentioned.
