What is the cause of bleeding after more than one month of pregnancy?

The first month of pregnancy is the most dangerous period of pregnancy. At this time, the test tube embryo is not yet very firm in the mother's body. Various problems are more likely to occur at this time. If you don't pay attention, it will often lead to problems such as miscarriage. Therefore, female friends must be very careful when they are one month pregnant. So what is the reason for bleeding one month into pregnancy?

1. What is the cause of bleeding one month into pregnancy?

Bleeding during one month of pregnancy is also a common condition in clinical medicine. It can be caused by many reasons. Bleeding during pregnancy can be divided into the following categories according to the source of bleeding:

1. Pregnancy bleeding caused by conditions at the maternal level is mainly caused by uterine disease or estrogen deficiency.

2. Pregnancy bleeding caused by the test tube embryo itself is mainly due to problems with the test tube embryo itself. If there are problems in these aspects, the situation is still not very optimistic.

3. Pregnancy bleeding caused by external stimulation. During pregnancy, the uterus and abdomen will be in a state of hematoma and will appear too fragile. Sometimes even a slight stimulation or a little exercise can cause bleeding.

Pregnant mothers should take appropriate measures according to their own conditions, see a doctor or do a self-examination.

2. What to do if you have bleeding one month into pregnancy

If vaginal bleeding occurs one month into your pregnancy, be sure to see a doctor as soon as possible.

The doctor will first assess the amount of bleeding and accurately measure blood pressure and pulse rate to determine whether immediate hospitalization is needed. Then the patient will be asked some relevant information, such as the date of the last menstrual period, whether the menstrual period is regular, whether morning sickness and breast pain have occurred before, and whether they still exist, and whether there is any lower abdominal pain. Then further physical examination will be carried out and a basic diagnosis will be made. If necessary, ultrasound examination and blood test will be arranged to test the serum for "beta-human chorionic stimulating hormone" (commonly known as chorionic growth hormone) or luteinizing hormone to help confirm whether it is a normal intrauterine pregnancy, miscarriage, ectopic pregnancy or hydatidiform mole.

For the test of chorionic villus hormone, it is generally more practical to compare the standard values ​​of two blood tests taken 48 hours apart. In patients with normal intrauterine pregnancy, the second standard value will generally be more than 66% higher than the first. If the increase is insufficient or there is a decrease, it may be ectopic pregnancy or incomplete abortion. At this time, hysterectomy or laparoscopy should be arranged for further diagnosis.

In recent years, due to the development of intravaginal 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 40,000; if no gestational sac is found in the uterus, and the hRH is higher than 1500 IU/L, the possibility of ectopic pregnancy must be considered.
