My period is 5 days late and i have little to no discharge i had sex two weeks ago with my boyfriend but a condom was used and it didn't rip. no symps?

Some thoughts...: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… Seeing a doctor is a good idea if symptoms are worrisome. Pregnancy is the common cause of a missed period, if sexually active. One can do a pregnancy test.
