Is AUTHOR wrong in the post ? POST : Hey all, first time posting 

My best friend has been seeing a guy for a bit now. They get along really well and today she lost her virginity to him. 

Problem is, they had unprotected sex and he did the deed inside her. 

She said she plans on buying Plan B in the morning. I remember reading studies about how BMI affects emergency contraceptives. Basically higher BMI women are at risk for emergency contraceptives being less effective.

She is overweight and it is a sensitive issue for her. I want to tell her to get two pills but A) it's more money and B) I feel like it would hurt her feelings. 

If I tell my friend to get two pills, WIBTA?

TLDR: My friend who is overweight had unprotected sex and I'm afraid telling her to get two pills would make me the asshole.
