Could you be pregnant if your period is one week late and lasted for 3 days?

Yes, it is possible to be pregnant if your period is one week late and lasted for three days. Pregnancy can occur any time a fertile woman has unprotected intercourse. A missed period is one of the most common early signs of pregnancy, but not all missed periods are due to pregnancy. Other factors, such as stress, illness, or changes in diet or exercise routine, can also cause a period to be late.

If you are concerned that you may be pregnant, it is essential to take a pregnancy test. Pregnancy tests are available at most drug stores and can be used at home. If the pregnancy test is positive, you should see a doctor to confirm the pregnancy and discuss your options.
