Hello doctor,

How effective is Plan B one step if taken less than an hour after sex? The condom broke and we also used vaginal contraceptive film with the condom.

Hi,

Welcome to icliniq.com.

Emergency contraceptives either work by preventing or delaying ovulation or implantation of a fertilized egg. So, it depends on how early is it taken after unprotected intercourse, or what period of the cycle is it taken. Vomiting, diarrhea, and some medicines do affect the efficacy, unfortunately. In your case, since you used vaginal film also, chances of pregnancy are bleak. But to rule out all chances, please do a pregnancy test, if you miss your periods. Hoping, that you get regular periods.
