A two-bar test proves that you are pregnant. Brown blood from the vagina may be a sign of preterm miscarriage, incomplete miscarriage, or ectopic pregnancy. In such cases, it is recommended to actively visit the hospital to have blood tests for HCG, progesterone and ultrasound to determine the cause of the bleeding and make a correct diagnosis. The development of the embryo can be determined by observing the doubling of HCG and the progesterone level. If you are more than 6 weeks pregnant, an ultrasound can also be done to check the condition of the fetus. If the HCG value is well doubled, progesterone is normal, or fetal buds can be detected by ultrasound, the fetal heartbeat is good, and there is not much bleeding, it means the fetus is developing well. Patients should pay attention to bed rest, prohibit sexual intercourse, and enhance nutrition appropriately. In case of luteinizing insufficiency leading to pre-eclampsia, the fetus can be treated by injection or oral fetal preservation drugs under the guidance of the doctor. In case of hypothyroidism, small doses of oral thyroid hormone medication can be taken under the guidance of a doctor. In case of incomplete miscarriage, timely clearance surgery is recommended. If the patient has heavy bleeding along with pain in the lower abdomen, it is recommended to go to the hospital for ultrasound examination in time to rule out ectopic pregnancy and to treat the symptoms according to the examination results.
