My Girlfriend Took 3 Plan B's This Month. Will This Delay Her Period?
It is possible for emergency contraception to delay her period when taken. We recently answered a question on Plan B and explain how it effects the menstrual cycle. Planned parenthood explains that even though taking plan B when needed does not cause negative effects, relying on a daily form of birth control can help ease the stress and anxiety of having to get plan B multiple times a month.
Since you mention your girlfriend has taken Plan B 3 times in one month, TeenHealthFX recommends that you and your girlfriend have a conversation and find a more consistent form of birth control.
In addition, TeenHealthFX encourages all teens to use condoms on every and any sexual encounter. Condoms 98% effective when used correctly and consistently in not only preventing sexually transmitted diseases, but also pregnancy.
