Day 10 of embryo transfer weak positive, has it already failed?

Patient's question:

No

Doctor's answer:

Hello, if your menstrual cycle is delayed by 7 days or you have had intercourse between 10 and 14 days, you can use a pregnancy test kit to check. If two red lines appear on the test paper, it indicates a positive result, meaning you are pregnant. Additionally, you can have a blood HCG test at the hospital 7 days after sexual intercourse.
