P> Just pregnant women will have some pregnancy symptoms more or less, but some women may be careless and don't pay too much attention to their bodies. Suddenly, her lower body bleeds, and she may be silly and confused, thinking that this is a monthly menstruation. So, how to distinguish between menstruation and pregnancy bleeding? How to distinguish between menstruation and pregnancy bleeding < P > Pregnancy bleeding first has a history of menopause, and the menstrual cycle time is more than one week. Early pregnancy test paper or B-ultrasound confirms that there is bleeding after pregnancy, a small amount of irregular bleeding, dribbling bleeding, excessive amount, and abdominal pain. Menstrual blood generally has a regular menstrual cycle, and comes on time, usually for 2-7 days, and the amount is 2-8ml, which may cause abdominal distension and pain, uterine contraction pain, etc. During menstruation, the color of menstrual blood is dark, and usually you can see something like debris (exfoliated endometrium). If it is pregnancy bleeding, threatened abortion, the amount of bleeding is less, significantly less than the amount of menstruation, the color can be pink, brown; If there is incomplete abortion, the amount of bleeding is large, which can be significantly greater than the amount of menstruation, and embryonic tissue can be seen; If it is a complete abortion, you can see a complete gestational sac. If it is ectopic pregnancy bleeding, it is mostly drip-like brown bleeding, and ectopic pregnancy abortion and rupture can be accompanied by severe abdominal pain. Menstrual blood has certain regularity; Pregnancy bleeding is irregular, and the amount is not as much as menstrual blood. You can also test whether you are pregnant first. If it is pregnancy bleeding, we should pay attention to the symptoms that may be threatened abortion, and try taking some anti-abortion drugs in time. If there is bleeding in the first trimester, it is still considered that it is caused by threatened abortion. Finally, go to the hospital for a check-up. If the gestational sac is good, you can take anti-abortion medicine according to the doctor's advice. Pay attention to rest and don't be too tired. What is the bleeding in the early pregnancy? < P > Before the placenta is completely formed, the embryo implantation is unstable, so many factors can cause abortion. When abortion occurs, the embryo will be separated from the uterine wall to varying degrees, and once the blood vessels on the separation surface rupture, it will cause vaginal bleeding symptoms. According to a medical research, more than 5% pregnant women can survive the bleeding in the early pregnancy and successfully continue their pregnancy. About 3% of pregnant women may have a miscarriage; In addition, nearly 1% of pregnant women may have ectopic pregnancy or other problems. Some pregnant women are worried that there will be abnormal vaginal bleeding in early pregnancy, and the baby will be unhealthy after successful abortion. Many studies show that more than half of the abortions are caused by the abnormality of the embryo itself, which is a natural elimination. If the pregnancy can continue, the fetus is generally normal. After vaginal bleeding in the early pregnancy, if the pregnancy can continue successfully, the proportion of fetal congenital abnormalities has not increased. Bleeding in early pregnancy is a symptom of pregnancy. There are various causes: fetal chromosome abnormality, maternal hormone secretion disorder, abnormal uterine development or acquired defects, immune system problems, virus infection, pregnant women suffering from chronic diseases, overwork, excessive pressure, too intense sexual life, drinking, taking too much caffeine or other foods that promote uterine contraction.
