What happens if you get a period 4 days after the last?

If you get your period four days after your last period, it's possible that you're experiencing an Intermenstrual bleeding (IMB). IMB, which is also called "spotting," refers to bleeding or spotting that occurs between regular menstrual periods. It can be caused by various factors, including hormonal imbalances, certain medications, stress, or underlying medical conditions. If IMB occurs once, it's usually not a cause for concern, especially when the bleeding is light and goes away on its own.

However, if the bleeding is heavy or persistent or if you experience other symptoms such as abdominal pain or unusual discharge, it's essential to consult your doctor to rule out any underlying health issues and get appropriate treatment. Additionally, if your menstrual cycle becomes significantly shorter or more irregular in general, it's important to talk to your healthcare provider for further evaluation and guidance.
