i had sex with my bf without protection and the next day i took all the tablet in postinor2 once, is it going to work? should i take another one?

Hi Anon,

Thank you for reaching out to EmpowHER with your health question!

I looked up the directions of taking Postinor 2 and it says you must take the first pill within 72 hours (3 days) of unprotected sex. Then 12 hours after the first pill, take the second pill in your pack. If you vomit within 2 hours of taking either pill, talk to your doctor for an additional one.

Here are the full instructions: http://www.myvmc.com/drugs/postinor-2/

When you take Postinor 2 correctly, it is very effective in helping prevent pregnancy. I hope this helps! Let me know if you have any other questions.

Best,
Erin
