Biochemical bleeding in early pregnancy is not painful. Biochemical pregnancy is caused by unsuccessful implantation of fertilized egg, which results in vaginal bleeding similar to menstrual flow. Only the blood HCG (human chorionic gonadotropin) test indicates pregnancy, and after the vaginal bleeding stops, the blood HCG will drop rapidly to non-pregnant status. Generally, the vaginal bleeding of biochemical pregnancy is not accompanied by abdominal pain, and the menstrual flow is slightly heavier than the usual menstrual flow. Occasional biochemical pregnancy does not need to be too nervous, does not affect the next pregnancy, and generally can continue to prepare for pregnancy after the next menstrual period. Meanwhile, you should pay attention to proper rest during the period of preparation for pregnancy, avoid exertion, strenuous exercise and staying up late, eat a light diet, and continue to take folic acid on time as prescribed by the doctor. However, if the recurrence of biochemical pregnancy should consult a doctor in order to identify the cause and actively treat the cause before preparing for pregnancy.
