Can having a cold delay your period?

Maybe, but unlikely: A cold by itself may not delay one's menstrual period, but serious mental or physical stress can disrupt one's cycle. Significant loss of appetite, which could happen during a bad cold, may also affect menstruation. If one is sexually active and usually has regular cycles, it is important to check a urine pregnancy test or contact a primary care doctor. Cycles of 21-35 days are considered normal.

Shouldn't : Your menstrual cycle should not be affected by an everyday cold. If you are late, consider taking a home pregnancy test or seeing a physician.

The average cold: Doesn't usually get you too sick. Although it might be able to delay a period, usually associate delaying period with illness which is a little more substantial than a cold.
