The presence of brown discharge in a woman at 46 days of pregnancy is an abnormal sign. If you have not checked the ultrasound at this time to confirm that the pregnancy is intrauterine as well as ectopic, you should consider the possibility of having an ectopic pregnancy. This is because when the fertilized egg is growing and developing outside the uterus, it may cause irregular vaginal bleeding due to the poor or narrow environment outside the uterine cavity. However, it is also important to consider that it is caused by the manifestation of pre-eclampsia. Therefore, it is important to go to the gynecology department of the hospital to have an ultrasound to confirm whether the pregnancy is intrauterine or ectopic, and to check the blood HCG and progesterone to see if there is low progesterone. If the miscarriage is considered to be pre-eclampsia, progesterone and progesterone can be considered for the treatment of the pregnancy.
