How many days does early pregnancy bleeding usually last?

Early pregnancy bleeding is a normal phenomenon. Generally, the bleeding from the implantation of the fertilized egg will last for 1-2 days, and the expectant mother will not feel any discomfort such as abdominal pain. If there is severe vaginal bleeding, you must pay attention and do not take it lightly. You must go to the hospital for testing in time to see if there are any symptoms of threatened abortion.

1) Fertilized egg implantation

After the fertilized egg is formed and reaches the uterus, it will implant into the endometrium and the implanted part will become the placenta in order to obtain nutrients from the mother. During the implantation process, it may cause rupture of endometrial blood vessels.

Due to physiological and physical problems, some mothers will absorb the bleeding quickly after bleeding, some mothers will have transient bleeding, and some mothers will continue bleeding for 1 to 2 days.

This type of bleeding is generally not accompanied by discomfort such as abdominal pain. All the mother needs to do is to keep it clean, which generally will not affect the development of the embryo.

2) Rupture of cervical mucosa

Why does the cervical mucosa rupture? This is mainly because as the fetus develops, the uterine body will be expanded, but the cervix will not be expanded. At the junction of the cervix and the uterine body, the endometrium and the uterine wall will be dislocated, and there may be a little bleeding at this time.

This type of bleeding usually begins to occur around 30 or 40 days into pregnancy and can last for one, two, a week, or two weeks. It can be intermittent or a little bit every day. The amount is very small, so small that most careless people won’t care about it, and so small that you may not feel anything, so pregnant mothers don’t need to worry too much.

2. Vaginal bleeding tends to increase

Vaginal bleeding occurs and tends to increase gradually, accompanied by symptoms such as abdominal pain, which is often diagnosed as "threatened abortion" clinically. However, most obstetricians and gynecologists currently believe that the diagnosis of "threatened abortion" is a controversial diagnosis. Many cases of abdominal pain and vaginal bleeding that occur in early pregnancy make it difficult to determine whether they are normal pregnancies or true "threatened abortions."

In early pregnancy, the spontaneous abortion rate is relatively high, and the vast majority of these aborted embryos have problems, which is the result of "survival of the fittest." If the amount of bleeding is more than the menstrual volume, and it becomes more and more frequent, or even bright red, in most cases the embryonic development has stopped. In this case, it is more accurate to say that it is "destined miscarriage" rather than "threatened miscarriage", and treatment to preserve the fetus is not recommended. To be on the safe side, a B-ultrasound is needed to confirm the condition of the fetus.

If the products of pregnancy are completely expelled, bleeding will gradually decrease and abdominal pain will be relieved, and generally no special treatment is required. If the products of pregnancy are not completely expelled, bleeding is still heavy, and abdominal pain is obvious, it is an incomplete miscarriage and emergency uterine curettage is required in most cases.

3. Vaginal bleeding, accompanied by abdominal pain and distension

In addition to bleeding, if the expectant mother also has persistent dull pain or soreness on one side of the lower abdomen, it indicates a high possibility of ectopic pregnancy. However, these few points alone cannot confirm an ectopic pregnancy. If a diagnosis is to be made, examination is still required. When blood HCG>2000IU/L and no intrauterine gestational sac is seen by vaginal B-ultrasound, the diagnosis of ectopic pregnancy is basically established.

In addition, regardless of whether there are signs of ectopic pregnancy, once pregnancy is confirmed, you should go to the hospital for examination as soon as possible to rule out ectopic pregnancy.

If the fertilized egg implants outside the uterine cavity, such as in the fallopian tube or ovary, the implantation site may rupture as the fetus develops. Once rupture occurs, the pregnant mother will suddenly feel tearing pain in the lower abdomen, often accompanied by nausea, vomiting, extreme pain, pale complexion, rapid heartbeat, decreased blood pressure, etc. The disease progresses rapidly and can lead to hemorrhagic shock, with serious consequences.

If you are a high-risk group with a history of ectopic pregnancy, adnexitis, or assisted reproductive conception, you need to seek medical attention immediately if bleeding occurs.

4. Vaginal bleeding, accompanied by abdominal pain and fever

This situation is mostly because the expectant mother is infected with pelvic inflammation or cervical erosion, cervical polyps and other diseases. A routine blood test may show signs of inflammation such as increased white blood cells, but these diseases can usually be discovered under careful examination by a specialist.

For vaginal bleeding caused by this reason, the primary disease should be treated promptly, otherwise it is very likely to induce miscarriage.
