What is the cause of sudden bleeding in 6 weeks of pregnancy?

Many women will experience sudden bleeding when they are six weeks pregnant. There are many reasons for this situation. It is very likely caused by threatened abortion or some pregnancy reactions. However, it is not ruled out that it is caused by problems in the female uterus. In the face of this situation, people need to pay special attention. The following is a detailed introduction to what is the cause of sudden bleeding in the sixth week of pregnancy?

If you bleed at 6 weeks of pregnancy, you first need to rule out ectopic pregnancy. Blood HCG, progesterone and B-ultrasound all need to be checked thoroughly. Secondly, you need to have a gynecological examination to see if there are cervical polyps, and also a B-ultrasound to see if there is any possibility of intrauterine bleeding or threatened abortion. If threatened abortion is considered and tocolytic treatment is needed, the patient should rest in bed and receive an intramuscular injection of progesterone, 20 mg at a time, for 3-7 consecutive days. Further treatment will then be performed based on the HCG value and the results of B-ultrasound review. If bleeding occurs at this time, some people are afraid of the possibility of missed abortion or embryo failure, so regular B-ultrasound checks and blood tests for HCG and progesterone are needed.

Bleeding at six weeks of pregnancy indicates threatened abortion. According to your test results, progesterone is low, and your B-ultrasound results show that the gestational sac is small and the human chorionic gonadotropin value is not very high. If your menstruation is regular, this may be a sign that the embryo has stopped developing. You can consider bed rest and progesterone treatment, and go to the hospital for a check-up in about a week. If the test results and B-ultrasound results have not changed, it can generally be determined that the embryo has stopped developing, and termination of pregnancy is generally required.

Because you are 6 weeks pregnant, the gestational sac should be around 1.5 cm when doing B-ultrasound, and sometimes the fetal heart and fetal bud can be seen. If vaginal bleeding occurs, it may be a threatened miscarriage or the fetus may have stopped developing. An ultrasound examination must be performed before the next step of treatment can be determined. If the fetal heart rate and embryo are normal, the fetus can be preserved with progesterone or Chinese medicine. If the embryo stops developing, a uterine curettage should be performed immediately. However, if you cannot see the fetal heartbeat or embryo at this time, you can continue to observe for 1 week. If there is still no sign after 1 week, it means that the embryo has stopped developing and you need to undergo immediate uterine curettage surgery.
