Dear whitegirl2507,

Having sex does not change a woman's period — unless she becomes pregnant as a result of unprotected vaginal intercourse. Women do not get their periods when they are pregnant. Once a pregnancy begins, a woman's body begins to release hormones to support the pregnancy. The hormones also prevent menstruation and ovulation.

Hope this information helps!

Take care,
