Hello doctor! My wife is 8 weeks and 2 days pregnant but still has a normal period. When my wife went to the hospital near my house, the sonographer said that my wife has a double uterus or a bicornuate uterus (each time the doctor said one type). Currently, the fetus is still developing normally, with a length of 17mm and a heart rate of 150.
So the doctor asked me: “Why is there a menstrual cycle while pregnant? or not and does it have any effect on the fetus? Thanks for the advice doctor!

Hello! With the question: Why is there still a menstrual cycle when pregnant? Your doctor will answer as follows:
The phenomenon of being pregnant and still having a menstrual cycle is very rare. Therefore, it is necessary to distinguish bleeding threatening a miscarriage from a menstrual cycle phenomenon. You should go to the doctor with your wife when bleeding at medical facilities specializing in obstetrics and gynecology to receive specific advice.

Black bleeding at 6 weeks pregnant, it's unclear if the gestational sac has any effect?

months ago, I had a history of miscarriage, then I had my period again normally, my menstrual cycle is 30 days, 4 days is over. On December 18, I had my period, on January 17, it was due but it was late until January 25. I tested with a stick and saw 1 faint line and 1 faint line. I went for an ultrasound and did not see the gestational sac. On February 1, I went for an ultrasound and the doctor said he saw the gestational sac but it was not clear yet, so I should continue to monitor. In the doctor's book, my gestational age was calculated to be 6 weeks but the gestational sac was not clear and I was also bleeding a little black blood, I also told the ultrasound doctor but he did not say anything. Doctor, can you tell me that I have black blood when I am 6 weeks pregnant, I do not know if the gestational sac has any effect? What is the cause of my black blood, doctor? Thank you doctor.

Bleeding in the early stages of pregnancy is okay?

My period is about 15 days late. I tested with a test stick and it showed two faint lines. But then I had a lot of brown bleeding. I went for a transvaginal ultrasound, the doctor did not see the gestational sac and asked me to do a beta HCG blood test. My result was 121. The doctor scheduled me to do another beta HCG test in 2 days. But today I have a lot of red blood like menstrual blood. So doctor, can you tell me if I am pregnant?

Why does 6 weeks of pregnancy stop developing, vaginal bleeding has the shape of a fetus?

Hello doctor! I am 6 weeks pregnant, I went to the doctor and was diagnosed with a fetal growth arrest because there was no fetal heartbeat, then I waited for a week and had abdominal pain and bleeding. I went to the hospital and the placenta had come out, the ultrasound doctor said there was nothing left but fluid and blood. That means I had a miscarriage, but 2 days later I had severe abdominal pain and the fetus was gone, the fetus was as small as a baby's little finger. So I would like to ask the doctor: "Why does a 6-week-old fetus stop developing and have vaginal bleeding but still have the shape of a fetus?" If I was still pregnant when the placenta came out, would the fetus still be alive? Thank you doctor for your advice!
