Doctor's answer:
Starting from the first day of your last menstrual period, you can check if you are pregnant. It's not easy to detect the embryo with an ultrasound at one month, but a color Doppler ultrasound can be used. Urine tests can be inaccurate and not always reliable, so that's why urine tests are performed. Ultrasound double check.
