If fresh vaginal bleeding occurs in the sixth week of pregnancy, it is a symptom of preeclampsia, although there is no abdominal pain, however, it is likely that this condition is due to the fact that the embryo is in a low position of attachment, and then there is a rupture of the capillaries between the uterine wall and the gestational sac, and bleeding occurs. It is recommended that, in addition to bed rest, an ultrasound should also be performed, mainly to find out whether the embryo’s condition corresponds to the number of days since menopause. Usually, if you are already six weeks pregnant, you can see the embryonic tissue on the ultrasound, and if you can see the embryonic tissue, it is a normal phenomenon. Then you should draw blood to check the blood HCG and progesterone, to find out whether low progesterone causes the symptoms of preterm miscarriage, and then you should be hospitalized to receive anabolic treatment if necessary.
