Hi, we just had an unprotected sex last night around 1am. Ive been researching about postinor 2, we planned to get 1 ASAP because the sooner, the better right. So my question, what if after the second pill has been taken, and she vomit later. Should she take another pill? What if she keeps vomiting? When should she stop taking the postinor 2? After finished taking 2 tablets? Thx!
