What's wrong with a little pain inside the vagina and a small amount of blood?

Patient's question:

Patient age: 24
Detailed medical condition and purpose of consultation: Slight pain in the vagina with a small amount of bleeding
Duration of this illness: 2 days

Doctor's answer:

There are many causes of vaginal bleeding, such as irregular menstruation, intrauterine device bleeding, and submucosal uterine fibroids. Sometimes, miscarriage or poor uterine involution after induced abortion can also lead to bleeding. Since it can be caused by many factors, patients should seek medical attention immediately upon experiencing this condition. Hospital examination is necessary, and procedures such as cervical scraping, colposcopy, diagnostic dilation and curettage, and hysteroscopy may be performed when needed to confirm the diagnosis and start treatment early.
It is recommended to maintain cleanliness and hygiene in the vaginal area, avoid sexual activity, and refrain from consuming spicy or irritating foods.
