When going off birth control should someone be worried that her period is now 5 days late?

It is relatively normal for menstruation to be irregular after stopping birth control, or to skip a period altogether depending on the type of birth control used.

When a person first starts or stops taking birth control, it can take several months for their menstrual cycle to regulate. For many, the first few cycles may be shorter or longer than usual, and some women may even ovulate twice in one month. Irregular bleeding or spotting can occur during the adjustment period as well. Other things that may affect a person’s cycle regularity after stopping birth control include underlying health issues and lifestyle factors such as stress and diet.

If an individual has an underlying medical condition or are experiencing concerning symptoms such as heavy bleeding or pain, it's always best to consult a healthcare professional. In general, it is suggested to give the body some time to adjust and return to a normal cycle before expressing concern.
