Plan B?

Aulbrey
So yesterday my bf and I had sex and the condom broke. Not even an hour later I took plan B. This is my first time using it, my period is always regular (starts in 10 days), and condoms are the only form of bc I use. So far, no symptoms except for occasional twitches in the ovary area. And I had just got out of my fertile window. Is it normal to have no symptoms?
