A woman's menstruation is at the end of the month, and it has not arrived by the beginning of the month. Is she pregnant?

Patient's question:

No

Doctor's answer:

It's not necessarily pregnancy? Since everyone's constitution is different, coming a few days earlier or later is considered normal. However, if you're worried about pregnancy but don't want to go to the hospital for a check-up, it's best to buy a pregnancy test kit to test it.
