When should I worry about a missed period? Gynecologist in Seoul, Korea
The short answer
Take a pregnancy test first. If it is negative, an occasional late period after stress or travel is common. See a gynecologist if you miss three periods in a row, your cycles are consistently longer than 35 days, or you also have pain, unusual hair growth, milky nipple discharge or weight changes.
Persistent absent periods can affect bone health and fertility, so they are worth checking. See pregnancy test and hormone testing.
