You got your period on the 7th then 22nd again what does this mean?

A shorter-than-usual menstrual cycle can be a sign of an underlying medical condition, such as:

1. Polycystic ovary syndrome (PCOS): PCOS is a hormonal disorder that affects women of reproductive age. It is characterized by irregular menstrual cycles, acne, excess hair growth, and weight gain.

2. Thyroid problems: Thyroid problems, such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), can also affect menstrual cycle length.

3. Stress: Stress can also cause irregular menstrual cycles. When you're under stress, your body produces more of the hormone cortisol, which can interfere with the production of other hormones, including those that regulate the menstrual cycle.

4. Pregnancy: If you are pregnant, your menstrual cycle will stop. However, some women may experience light spotting or bleeding during early pregnancy.

5. Infections: Infections of the reproductive system, such as pelvic inflammatory disease (PID), can also cause irregular menstrual cycles.

It's important to see a doctor if you are concerned about your menstrual cycle length. Your doctor can help determine the cause of your irregular cycles and recommend treatment, if necessary.
