If brown discharge occurs at 8 weeks of pregnancy, it is often caused by the following reasons: first, the body’s progesterone deficiency, which causes contraction of the smooth muscle of the uterus, peeling between the uterine wall and the gestational sac, bleeding after the rupture of capillaries, and this bleeding does not drain outside the uterine cavity in time, but accumulates in the uterine cavity and is discharged only after a few days, and the original blood becomes stale bleeding. This is why there is a coffee-colored discharge. It is recommended to rest in bed and to give the necessary anti-fetal treatment to suppress the contraction of the smooth muscle of the uterus. Secondly, it is possible that the embryo has stopped developing, which is the reason for the brown discharge, often accompanied by the sudden disappearance of the pregnancy reaction and the absence of breast tenderness. It is advisable to pay attention to this situation and first do an ultrasound examination to understand whether the embryo is developing normally before deciding on the next step of treatment.
