pls can postinor works for those that have irregular period?

Hi Anon,

Thank you for sharing your question with the EmpowHER community.

The emergency contraception product Postinor 2 will work if you take it as instructed regardless of your menstrual cycle being regular or irregular. However, one of the main side effects is irregular menstrual cycle, so changes of menstrual characteristics is to be expected.

As for how long sperm can last inside a woman's body, depending on the conditions, up to 5 days.

I hope this helps.

Be well,
