No and no: Plan b is simply a higher dose of hormones found in oral contraceptive medication. Why don't you go on the pill rather than using this repeatedly? It does not cause either infertility or breast cancer as far as anyone knows.

No: Use of Levonorgestrel (plan b) pills will not affect future fertility. Although there has been some evidence to show that combined (estrogen + progesterone) pills may increase the risk of breast cancer, this has not been demonstrated with Progesterone only contraception such as levonorgestrel.

Plan B: Plan b is only a high dose of birth control medication. You run the same risks taking Plan B as you would taking birth control however you do not take it for long periods of time rather you just take high doses occasionally when needed. If you are concerned about the side effects of taking birth control you may want to look into using different methods of birth control rather than hormones. I do not believe there is any documentation supporting infertility.

No information: Since Plan B was developed and is marketed as emergency contraception (morning after pill) the effect of repeated use has never been studied. This is important; if you need or desire regular contraception, please use a product that has been studied and shown to be safe and effective for this purpose rather than repeatedly using a product intended for emergency use only!
