If you think you are pregnant, you may want to test yourself at home with a home pregnancy test. You can buy kits at a drug store without a prescription.
Home use kits measure a hormone called human chorionic gonadotropin (HCG) in your urine. The hormone can be detected in urine about 2 weeks after conception (when the egg is fertilized by the sperm). Most home kits require specific timing, materials, and sample amounts. You should also check the expiration dates and storage conditions before performing a test to make sure the components still work correctly. To get the best results, follow the instructions that come with the kit, read the label and instructions carefully. When in doubt, contact your health care provider. All tests can give false results (meaning the test indicates you are pregnant but you may not be, or the test says you are not pregnant and you are). You should see your health care provider if you believe the test results are wrong or to confirm the results.
Health Services also performs pregnancy tests at no charge. The Center for Sex and Gender Relations sells pregnancy tests for a nominal fee.
