How many times should a pregnancy test be taken to be fully accurate?

Patient's question:

No

Doctor's answer:

Generally, if your next menstrual period is more than 10 days away, it may be possible. Usually, 8-10 days after sexual intercourse, you can confirm whether you are pregnant by having a blood test for HCG. This is currently the earliest and most accurate method. It is recommended to use a pregnancy test kit after your menstrual cycle is delayed by 7 days. It is relatively accurate. Two red lines appearing on the test paper indicate a positive result, meaning you are pregnant.
