Five months pregnant and having vaginal bleeding - what's the cause?

Patient's question:

No

Doctor's answer:

The first consideration for bleeding in the second trimester of pregnancy is low-lying placenta, followed by threatened miscarriage, and thirdly, cervical erosion. Since the ultrasound shows the placenta attached to the anterior wall, the possibility of a low-lying placenta can be ruled out. The vaginal bleeding is likely due to threatened miscarriage or cervical erosion. It is recommended to rest in bed, take oral medication for fetal preservation and hemostasis, maintain good hygiene of the external genitalia, and the condition will gradually improve. Avoid sexual activity.
