How long does it take for bleeding to occur during pregnancy?

Generally speaking, bleeding will not occur during pregnancy. Only slight bleeding may occur in the early stages of pregnancy, but it is not too serious. If the amount of bleeding is too heavy, it is abnormal. In this case, you can only seek treatment to avoid miscarriage caused by excessive bleeding. In addition, you should pay attention to rest. It is best to stay in bed and rest more during bleeding.

For early pregnancy, especially threatened miscarriage shortly after menopause, the main focus is to observe the possibility of continuing the pregnancy. The main auxiliary diagnostic methods are B-ultrasound and blood hCG level testing. In normal early pregnancy, the blood hCG level has a doubling time, and blood hCG can be measured continuously to understand the condition of the fetus. If the blood hCG level increases by less than 65% every 48 hours, it may indicate a poor prognosis for the pregnancy. At the same time, continuous monitoring by B-ultrasound is also of great significance. For example, if only the gestational sac is seen but the fetus is not seen for a long time or if the fetus is present but the fetal heartbeat is not seen for a long time, it may indicate a poor prognosis.

1. There is a small amount of vaginal bleeding and mild paroxysmal uterine contractions in early pregnancy. The cervix is ​​not dilated and the size of the uterus is consistent with the number of months of amenorrhea.

2. Positive pregnancy test.

3. Ultrasound examination shows fetal heartbeat, gestational sac and fetal movement.

4. Methods for estimating the prognosis of miscarriage:

① If the keratinized cells in the vaginal cell smear exceed 30%, the prognosis is usually poor.

②Basal body temperature measurement in early pregnancy:

Patients with signs of miscarriage but whose body temperature does not drop have a good prognosis, while those with a lower basal body temperature have a poor prognosis.

③ Human chorionic gonadotropin (HCG) determination:

If the level of chorionic gonadotropin decreases gradually, the prognosis is poor.

In addition to bed rest and strictly prohibiting sexual intercourse, the treatment of threatened abortion should create an environment that is conducive to stabilizing the patient's mood and relieving tension. For those with a history of miscarriage, more spiritual support should be given. If the pregnant woman's progesterone level is low, progesterone supportive therapy can be used.

1. For unplanned pregnancies or those with estimated poor prognosis, artificial abortion should be performed as soon as possible.

2. For those who meet the requirements of family planning, if ultrasound examination or continuous HCG measurement indicates that the fetus is alive, pregnancy preservation should be provided.
