How effective is Postinor 2 if taken within 24 hours of unprotected sex? How to know if the pill actually worked?
I had an unprotected sex with my boyfriend a week ago. The same night I started having bad cramps. Does that mean the pill worked? Since this is my first time taking that pill I’m nt sure. I also consumed pineapple fruit n juice 3days after that.

Hello and good evening. Thank you for your questions.

For your information, Postinor 2 can be taken up within 72 hours of unprotected sex with its agreeable effectiveness as for your contraceptioin. Make sure that you took the pill for every 2 hours, with no more than 72 hours difference between each pill (incase you forgot).

To know the effectiveness of the pill, we suggest that you observe your menstrual cycle. If menstrual bleeding do come out anytime around the expected date of menses (like a normal period), it means that the pill is working effectively.

There is no evidence that states having bad cramps is a sign of effectiveness of the pill. However, bad cramps after using the pill is a common side effect for Postinor 2 that should not be taken lightly, especially if it happens for a length of time. We suggest you to consult your doctor if you are experiencing other side effects of Postinor 2 such as:

  • Nausea and vomiting
  • Breast pain
  • Irregular periods
  • Painful menstruation or period pains that is not related with your menses.
  • Headaches
  • Allergies

Your period late? Get a confirmation and don’t be in the dark anymore.

So far, there is no proven correlation or studies that relates contraception and pregnancy with consuming Pineapple fruit.
