Took Plan B and now you're on edge? It's understandable. While Plan B is effective at preventing pregnancy when taken correctly, it's not foolproof. Knowing the potential signs of failure can help you take timely action.
First, don't panic if your period is slightly early or late. Plan B can disrupt your cycle. However, a significantly delayed period (more than a week) is a key sign. Take a pregnancy test for confirmation.
Other signs, though less reliable, include continued pregnancy symptoms like nausea, breast tenderness, or fatigue. These symptoms can also be caused by other factors, but it's best to investigate.
Remember, Plan B is most effective when taken as soon as possible after unprotected sex. If you're concerned, take a pregnancy test a few weeks after taking Plan B to be sure. Early detection allows for more options and informed decisions.
