The answer
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. If you need help finding a doctor and live in northern New Jersey, you can call the [Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist.
