Many mothers-to-be experience a preterm miscarriage in the third trimester, such as mild abdominal pain or a small amount of bright red or brown bleeding. Many people are very nervous. Here is my advice: If the gestational week is very early and ultrasound has not been done, it is recommended to go to the hospital for an ultrasound at about 40 days of menopause (usually if the period is normal, intrauterine pregnancy can be confirmed at 40 days, and the fetal heart can usually be seen at 50 days) to confirm whether the pregnancy is intrauterine (mainly to rule out ectopic pregnancy); if the ultrasound confirms that the pregnancy is intrauterine, the next thing to clarify is that the bleeding is really from inside the uterus? Or is it in the cervix? Therefore, it is advisable to go to a gynecological clinic and let the doctor rule out the presence of cervical erosion or polyps (because many pre-eclamptic miscarriages are preserved for a long time, but turn out to be cervical problems). The last thing you need to do is to rest in bed, relax, and not be overly nervous or go to the hospital repeatedly.
