Glittergirl88 is right plan b prevents the egg from attaching to the wall so most likely not... There is still a chance but as long as she wasn't taking any medicines to cancell the plan B out she shouldn't be pregnant
She's most likely not pregnant. Plan B prevents the egg from attaching to the uterus wall. And that is IF she even ovulated.
She should of started her period.....if she didnt there may be a problem
How long ago was this and has she tested? It sounds like to me that there Ia a possibility.
