What is the cause of bleeding at 40 days of pregnancy?

Bleeding 40 days after giving birth is considered late postpartum hemorrhage. Most of them are caused by residue in the uterine cavity. You need to go to the hospital for physical examination and B-ultrasound to understand the condition of the uterine cavity. If residue is found in the uterine cavity, you should immediately perform medical abortion and uterine curettage. It may also be caused by incomplete uterine repair. If the uterus is found to be relatively large during gynecological examination and has not recovered to its normal size before pregnancy, you can use Motherwort Granules or Neobiochemical Granules to promote uterine contractions and return for a follow-up visit after one week of treatment.

Another possible cause of bleeding is postpartum infection. This type of bleeding is usually in small amounts, accompanied by fishy or even purulent discharge. It is necessary to take samples for analysis and drug sensitivity testing, and treat accordingly based on the results. In addition, pregnancy trophoblastic diseases, cervical lesions and bleeding should also be eliminated.

If there is a little bleeding around 40 days of pregnancy, it may be a symptom of threatened abortion caused by fatigue, threatened abortion caused by low progesterone during pregnancy, vaginitis in the patient, or cervical polyps, which may cause vaginal bleeding during pregnancy. If this happens, you should go to the hospital immediately to see a doctor to find out the cause and have an ultrasound examination to understand the size of the gestational sac and the site of embryo implantation. It is necessary to check the progesterone level, blood HCG test, gynecological physical examination, and leucorrhea examination to find out whether there is trichomoniasis vaginitis, whether there are cervical polyps, whether there is erosion and other reasons for bleeding, and give reasonable treatment according to the test results. If the progesterone level is low during pregnancy, it is necessary to replenish the progesterone level in time for pregnancy protection treatment.

If there is a little vaginal bleeding at 40 days of pregnancy, it is recommended to do an ultrasound examination. The first thing to know is whether it is an intrauterine pregnancy or an ectopic pregnancy. If it is an intrauterine pregnancy, it is necessary to understand whether the size of the gestational sac is consistent with the number of days of amenorrhea. For most women with normal menstruation, yolk sac will be seen through B-ultrasound examination around 40 days of pregnancy, which is a normal phenomenon. It is necessary to draw blood to check the blood HCG and progesterone levels to understand whether the values ​​of these two indicators are normal. If intrauterine pregnancy has been confirmed and there is a decrease in progesterone, bed rest is required. Progesterone copper can be injected intramuscularly, which mainly inhibits the contraction of uterine smooth muscle and plays a role in nourishing the fetus. While nourishing the fetus, it is also necessary to increase nutrition, which is beneficial to the growth and development of the test tube embryo.
