"I have a 7-day delay in my period (but negative pregnancy test). I am usually quite regular. Why?"

A delayed period of 7 days can be caused by various factors, including pregnancy. It is recommended to take a pregnancy test every few days to monitor hormone levels. Other possible causes of a late period include stress, which can affect ovulation timing. In the context of trying to conceive, it is suggested to engage in sexual intercourse randomly or every two days.
