If you have coffee-colored discharge on the 50th day of pregnancy, it is not normal and you need to go to the hospital for examination as soon as possible. It may be caused by preterm miscarriage, embryo stopping development and cervical polyp may also have coffee-colored discharge. If you go to the hospital for ultrasound examination, if you see a gestational sac in the uterine cavity with a fetal heart and a fetal bud and coffee-colored discharge, it may be caused by preterm miscarriage and requires fetal preservation treatment. If there is no polyp in the cervix and the bleeding is coming from the uterine cavity, it is also necessary to keep the fetus. If there is no fetal heart and fetal bud at this time, the embryo has stopped developing and an abortion is needed as soon as possible.
