What is the reason for having another period one week after the previous one just ended?

Patient's question:

No

Doctor's answer:

It is recommended to have an ultrasound examination at the hospital to understand the condition of the endometrium and ovaries. If everything is normal, you can take traditional Chinese medicine for regulation, such as Dingkun Dan, Danggui Wan, and Wuzhijibafeng Wan, etc. If the regulation is ineffective after 2 months, you should have a sex hormone test to rule out endocrine disorders causing menstrual irregularities, and then adjust the treatment accordingly.
