Is it normal if your period begins and is then stops gets light again when should be over?

Menstrual cycles can vary from person to person, and some variation in flow is normal. However, abrupt changes in flow, particularly if accompanied by other symptoms, can be a cause for concern. If you have any doubts or concerns about your menstrual cycle, it's always best to consult with a healthcare professional.

Possible explanations for your experience could include:

1) Hormonal Fluctuations: Menstrual flow is influenced by hormonal fluctuations, and it's possible to experience temporary changes in flow due to hormonal imbalances or fluctuations.

2) Implantation Bleeding: If you are of reproductive age and sexually active, there's a chance that the initial light bleeding could have been implantation bleeding, which occurs when a fertilized egg implants in the uterus. This bleeding is often lighter than a regular period and may stop or turn into a heavier flow later on.

3) Uterine Abnormalities: In some cases, uterine abnormalities such as polyps or fibroids can cause irregular bleeding. These growths can disrupt the normal shedding of the uterine lining, resulting in abnormal flow patterns.

4) Hormonal Contraceptives: If you are using hormonal contraceptives, such as birth control pills, they can affect your menstrual cycle and cause changes in flow.

5) Medical Conditions: Certain medical conditions, such as thyroid problems, clotting disorders, or pregnancy complications, can also impact menstrual flow.

It's worth mentioning that abrupt changes in flow can sometimes indicate an underlying medical issue, especially if they are accompanied by other symptoms such as severe pain, fever, or changes in the color or odor of the flow. Therefore, it's important to seek medical advice if you experience significant changes or concerns regarding your menstrual cycle.

Your doctor can evaluate your symptoms, provide a diagnosis, and recommend the appropriate treatment or management strategies.
