32 years old, menstrual period is advanced, the period becomes shorter, what tests should be done

Patient's question:

Menstruation is 3 to 7 days early, the period was originally 6, 7 days, now it's gone in 4 days, this has been the case for 2 years

Doctor's answer:

Hello, a normal menstrual cycle is 21—35 days, with an average of 28 days. The duration of menstruation is 2—8 days, with an average of 3—5 days. For each individual, it varies, as long as it falls within their regular pattern, it is considered normal. If you have your period every two days, that can also be considered normal.
