How many times can you take Plan B before you become infertile?

From what I understand, plan b doesn’t cause infertility – it simply has higher doses of hormones found in regular birth control pills.

Backing up @Simone_De_Beauvoir. There is no evidence suggesting any amount of Plan B makes you infertile.

Oh! I see, I heard from somewhere you could. >.<

Plan B will not make you infertile, but having unprotected sex raises your risks, because some very common STD’s can cause scarring around the ovaries and tubes.
