Iv taken plan b 2 times in the last 2 months. is it possible that could make my period late?

Periods with Plan B: Periods can get very off schedule with the use of Plan B. Don't be too concerned though, about unusual timing of periods after using Plan B. You have put very unusual amounts of hormones into your body with the Plan B and it really can throw things way off. That's how it works. You're just having the bleeding associated with Plan B use. You may or may not get your regular period this month.
