The following guidelines will help you determine the severity of your vaginal bleeding.
- Severe bleeding means you are soaking through your usual pads or tampons each hour for 2 or more hours. For most women, soaking through their usual pads or tampons every hour for 2 or more hours is not normal and is considered severe. If you are pregnant: You may have a gush of blood or pass a clot, but if the bleeding stops, it is not considered severe.
- Moderate bleeding means that you are soaking more than 1 pad or tampon in 3 hours.
- Mild bleeding means that you are soaking less than 1 pad or tampon in more than 3 hours.
- Minimal bleeding means "spotting" or a few drops of blood.
- Up to 25% of pregnant women have some spotting or light vaginal bleeding. Of these women, about 50% do not have a miscarriage. Vaginal bleeding during pregnancy is more common among women who have been pregnant before than in women who are pregnant for the first time.
- Very early spotting sometimes occurs when the fertilized egg implants in the uterus. Implantation takes place 6 to 10 days after fertilization.
Bleeding in the second or third trimester of pregnancy may mean a problem is present, such as:
- Placenta previa. Normally, the placenta is attached to the top portion of the uterus. In placenta previa, the placenta has attached low in the uterus, and partially or completely covers or blocks the cervix.
- Abruptio placenta. Normally, the placenta is firmly attached to the uterine wall until birth. If the placenta separates from the uterus before the baby is delivered, this is called abruptio placenta or placenta abruptio or placental abruption. Abruptio placenta usually occurs in the third trimester of pregnancy, but it can occur any time after the 20th week.
