I had my period last week and it was really light and lasted for 7 days but after it stopped a day later it came back and was really heavy is this normal or is something wrong?

Experiencing a light period followed by a heavy one shortly after can happen, but it’s not typical. Variations in menstrual flow can be influenced by stress, hormonal changes, or other factors. However, if this pattern continues or if you experience additional symptoms like pain or significant changes, it's best to consult a healthcare professional to rule out any underlying issues.
