What is the cause of a small amount of bleeding in early pregnancy?

Many people will experience a small amount of bleeding in early pregnancy. There are many reasons for this situation. It may be a sign of miscarriage or it may be caused by the shedding of the female's endometrium. In the face of this situation, people need to pay special attention to it and understand the reasons in detail to prevent any bad situations. Here is a detailed introduction to what is going on with a small amount of bleeding in early pregnancy?

Vaginal bleeding during early pregnancy may be physiological bleeding, but it may also be a sign of threatened abortion. During early pregnancy, changes in hormone levels in the body may cause irregular shedding of the endometrium. At this time, the bleeding should be relatively small and the patient should not have other discomfort symptoms. The bleeding will disappear in a short time as long as the color ultrasound proves that the gestational sac in the uterine cavity develops normally. However, if the amount of bleeding is heavy, and there is a feeling of heaviness or hardness in the abdomen during or before bleeding, it may be caused by uterine contractions, which are obvious symptoms of threatened abortion and you should go to the hospital for examination in time.

Treatment measures:

The doctor will first assess the amount of bleeding and measure blood pressure and pulse to determine whether immediate hospitalization is needed. The patient will then be asked some relevant information, such as the date of the last menstrual period, whether the menstrual period is regular, whether she has ever experienced morning sickness and breast tenderness and whether these symptoms still exist, and whether she has symptoms of lower abdominal pain. Then further physical examination will be carried out and a preliminary judgment will be made. If necessary, an ultrasound examination and blood test for serum levels of "beta-human chorionic gonadotropin" (abbreviated as chorionic hormone) or progesterone will be arranged to help diagnose whether it is a normal intrauterine pregnancy, spontaneous abortion, ectopic pregnancy or hydatidiform mole.

Regarding the examination of chorionic villus, it is usually more valuable to compare the values ​​of two blood draws 48 hours apart. In patients with normal intrauterine pregnancy, the second value will usually be more than 66% higher than the first. If the increase is not enough or there is a decrease, it may be an ectopic pregnancy or incomplete abortion. At this time, uterine dilatation and curettage or laparoscopy should be arranged for further diagnosis.

In recent years, due to the development of vaginal ultrasound, its resolution has been greatly improved, which can help doctors detect intrauterine gestational sac earlier. If an intrauterine gestational sac is found, the chance of ectopic pregnancy at the same time is very low, about only one in forty thousand. If no gestational sac is found in the uterus and the chorionic hormone is higher than 1500 IU/L, the possibility of ectopic pregnancy must be considered.
