If you don’t use test strips, you can find out if you are pregnant by taking a blood test for blood HCG. If the blood HCG value is greater than 10 mIU/mL, it indicates pregnancy. In addition, ultrasound can also be done clinically. Most people will see the gestational sac in the uterus through ultrasound around 40 days of pregnancy, which can also check if they are pregnant. Therefore, it is possible to find out if you are pregnant by taking a blood test or ultrasound without using test strips, and to find out how many days you are pregnant. It is best to take a blood test after 31-32 days of menopause to find out if you are pregnant. In the case of ultrasound, it is better to check if you are pregnant by ultrasound around 40 days after menopause.
