My daughter is 11 recently has been going through mood changes she also experiencing puberty but had her period yet it possible for to be PMSing?

It is possible for your daughter to be experiencing premenstrual syndrome (PMS) even though she has not yet had her first period. PMS is a group of symptoms that occur in the days or weeks leading up to a woman's period. The most common symptoms include mood swings, cramps, bloating, fatigue, and headaches. Some women also experience acne, breast tenderness, and changes in appetite or sleep patterns.

The exact cause of PMS is not known, but it is thought to be related to the hormonal changes that occur during the menstrual cycle. These changes can affect the brain and cause mood swings, irritability, and other symptoms.

PMS can typically be managed with lifestyle changes, such as getting regular exercise, eating a healthy diet, and getting enough sleep. Over-the-counter medications, such as ibuprofen or naproxen, can also be helpful in relieving symptoms. In some cases, a doctor may prescribe birth control pills or other medications to help manage PMS.

If your daughter is experiencing PMS, it is important to talk to her about it and let her know that she is not alone. You can also help her find ways to manage her symptoms and make her feel more comfortable.
