Question
Hello doctor,
7 months ago I had a history of stillbirth, then I had a normal period again, my menstrual cycle is 30 days, 4 days is over. On December 18, I got my period, on January 17 it was the day of my period but it was delayed until January 25. I tested it and found 1 faint line 1 faint line. I went for an ultrasound and didn't see a gestational sac. On February 1st, I went for an ultrasound, the doctor said that the gestational sac was found but it was not clear, so I should monitor it more. In the doctor's book, my gestational age is 6 weeks, but the gestational sac is not clear and I am also bleeding a little bit of black blood, I also told the ultrasound doctor but the doctor said nothing. The doctor asked me if I had black blood when I was 6 weeks pregnant, it is unclear if the gestational sac has any effect? What is the cause of my black blood, doctor? Thank you doctor.

Hello,
To the question “Black bleeding at 6 weeks pregnant, it is unclear if the gestational sac has any effect? ", the doctor would like to answer as follows:
Vaginal discharge is a common phenomenon during pregnancy, encountered in about 25% of pregnant women in the first 12 weeks. Brown discharge during pregnancy can appear when the amount of blood to the uterus increases, concentrating in the cervix, making the intimate area more sensitive. In addition, brown vaginal discharge can also be pregnancy blood, some threatened miscarriage, stillbirth or vaginal infection,...
From your last menstrual period, it can be predicted on January 2. You go to ultrasound your gestational age is about 6 weeks, at this time the pregnancy ultrasound may still have a condition that does not clearly see the gestational sac. You should follow up according to the instructions of your doctor, check or ultrasound again after 10 days to assess the development of the fetus.
