Menstrual history: She had her period on the 5th of last month, but this month she only had it on the 15th. On the 25th, she took the post-coital pill. Her period only lasted 4 days, but the flow was very light, almost like the third day of a normal period.

Doctor's answer:

The Causes 1. It could be whether pregnancy occurs after love-making 2. Whether there is psychological stress causing an imbalance.
If not the first, go to the hospital to get some medication, and it will be fine after taking it.

Therefore, it's best to have a gynecological examination in the hospital's gynecology department, identify the cause, and then treat accordingly. Pay attention to dietary regulation in daily life, eat light and easily digestible foods, and avoid spicy, stimulating, and cold foods.
