Calculate menstrual cycle and ovulation date

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?

My name is Nga, I am 45 years old, 1.54m tall, and weigh 47kg. I just got married and really want to have children. My period is regular every month, nothing unusual. My husband is also 45 years old, doesn't smoke or drink alcohol. Neither of us have any diseases. My husband and I have sex regularly twice a week.

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!

Hello doctor! I have menstrual disorders, for 2 months now I still haven't seen it. After going to a private clinic, they gave me medicine to drink to induce menstruation including: 1 pack of round white pills, 1 pack of daily birth control pills. The doctor instructed me to take the round white pills for 10 days, then stop taking the medicine and my period will come for 2-7 days. When my period comes on the 2nd day, I will take the daily birth control pills. But when I took the round white pills, I felt dizzy even though I had eaten. I took the 2nd pill and my period came, so I stopped taking the medicine. I went to the clinic where I was prescribed the medicine and asked, the doctor said the medicine would cause dizziness after taking it and told me to take the daily birth control pills as prescribed, and when I finished the medicine, come back for a check-up and continue treatment. I am very worried, maybe it is because I am stressed or have changed my lifestyle causing menstrual disorders. Will the medicine the doctor gave me have any effect? And will taking birth control pills regularly like that cause infertility? I hope the doctor can advise me, thank you doctor.

Hello Doctor. I was born in 1995 and am pregnant. I will give birth in March 2020. So I want to get vaccinated against cervical cancer at the end of the year, is that okay? Thank you, Doctor.
