Hot flashes, dark spots appear due to endocrine disorders?

Hello doctor, how many weeks old is a fetus when there is a heartbeat? My wife had an ultrasound and the doctor said the fetus is 8 weeks old but there is no heartbeat and said the fetus is stillborn. What does this mean?

Hello doctor. I want to ask the doctor, we just got married and had sex without using any protection, and after a while I wanted to take my wife to get the HPV vaccine for cervical cancer, and I took my wife to do a pregnancy test and there was no sign of anything, and I decided to take my wife to get the HPV vaccine for cervical cancer, and after 1 month of the injection, my wife had a late period, and I asked the doctor at the injection site and the doctor said it might be because the injection was messed up, and continued to get the flu vaccine before getting pregnant, and a few days later I tested my wife and there were 2 lines, and I took my wife for an ultrasound, the doctor said it was 4 weeks and 4 days, I was so worried, I couldn't eat or sleep since that day, my wife got the first shot, doctor, can you tell me if the two vaccines for cervical cancer and flu affect the fetus, I hope the doctor will let me know and what I should do What is it, doctor, please tell me honestly, thank you!

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?

had the contraceptive implant for 3 months. The first 2 months I had bleeding like menstrual bleeding. On the 3rd month, on October 27th, I had my period. Today, November 15th, my period has not come yet. I saw a little bleeding. I am so worried!

Hello doctor. My test result is negative for Rubella IgM and positive for IgG (1189.3). Is my pregnancy okay? Thank you, doctor.
