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.
