Q: How do home pregnancy tests work?

A: These tests measure hCG levels in your urine.
hCG, a pregnancy hormone, appears shortly after you get pregnant. You'll see a positive result once the test detects hCG.

Q: Are there different types of home pregnancy tests?

A: Yes.

  • Early - Can deliver results quicker.
  • Non-digital - Shows results with lines.
  • Digital - Shows results with words.
  • Sticks and strips - Pee directly onto sticks. Dip strips in urine.

Q: When should I take a pregnancy test?

A: Wait until the day your next period is expected. That's about 19 days after sperm meets egg. If you take a test too soon, you'll get a negative result, even if you actually are pregnant.

Q: Do pregnancy tests ever expire?

A: Yes, usually after two to three years. Check the box.

Q: How accurate are home pregnancy tests?

A: 75% (approximately). Make sure you follow the instructions. Don't drink too much liquid before.

Q: Does a faint line mean a test is positive?

A: A faint line usually means positive, but test again a few days or weeks later to make sure.

Q: Can you get a false positive or false negative?

A: You can get a false positive or negative, although false negatives are much more common. If your test is positive, it's likely you're expecting! If you take a test too early or don't follow instructions, you might get a false negative. Either way, it's a good idea to confirm the results with your doctor.
