What should I do if I take a pregnancy test with two light bars and bleed like I’m menstruating?

The two bars of the pregnancy test are relatively shallow, and the bleeding is like menstrual flow, you need to consult a doctor in time through the blood human chorionic gonadotropin test and gynecological ultrasound to clarify whether there is a pregnancy and the specific situation, it may be a biochemical pregnancy, a priori miscarriage, etc., according to the specific conditions to take targeted treatment.
If the pregnancy test paper shows two bars, i.e. positive, the result is pregnancy. If the second bar is very light, it may be the formation of a fertilized egg but failed to successfully implant and develop, but only a transient elevation of chorionic gonadotropin in the body, i.e. biochemical pregnancy, the bleeding is equivalent to a delayed menstruation, and the amount and time should be basically as usual, so it can be left untreated for the time being, but if there is a lot of bleeding, it is necessary to consult a doctor in a timely manner.
The two bars on the pregnancy test paper are relatively shallow may also be the fertilized egg has just been laid and developed, the urine chorionic gonadotropin elevation is not obvious, this time the bleeding may be a pre-eclampsia, or has already appeared a pre-eclampsia, the body of the chorionic gonadotropin began to decline, resulting in the results of the pregnancy test paper is relatively shallow, need to consult a doctor in time to clarify the specifics of the situation.
If there is only light bleeding and the development of the fetus is normal, you can use progesterone, dydrogesterone tablets and other drugs under the guidance of the doctor to protect the fetus. If the bleeding is heavy or the development of the fetus is abnormal, it is necessary to terminate the pregnancy in time.
If abnormalities occur, you need to consult a doctor to clarify your condition, and do not treat the condition on your own, so as not to delay and aggravate the condition.
