Menstruation is delayed by more than twenty days. The ovulation test kit shows negative. Is it pregnancy?

Patient's question:

No

Doctor's answer:

As you mentioned, there is a possibility of pregnancy if contraception is not used. It is recommended to use a pregnancy test kit after a 7-day delay in the menstrual cycle. Additionally, two weeks after sexual intercourse, blood HCG tests can be used to confirm whether pregnancy has occurred.
