What Happens If You Take Plan B Too Many Times?

Taking Plan B multiple times is generally safe but not recommended as regular contraception. The FDA states there's no medical limit on emergency contraceptive use, but frequent use can cause irregular menstrual cycles, nausea, and hormonal disruption. Studies show Plan B is 89% effective when taken within 72 hours but loses efficacy with repeated use in short periods. Side effects like spotting, breast tenderness, and cycle disruption become more pronounced with frequent use. Regular birth control methods like pills, IUDs, or implants provide better protection and fewer side effects than relying on emergency contraception repeatedly.
