A 31-year-old member asked:

What are the chances my urine pregnancy test result was accurate?

It depends on test: Each company that makes a urine pregnancy test has a level(sensitivity) at which the test will convert to positive which is not zero so as to avoid false positive tests. That information is usually printed on the insert inside or on the box.Most tests convert to positive after a woman has missed her period by 5 to 14 days.

Depends: Home pregnancy tests measure the amount of beta human Chorionic Gonadotropin hormone in urine. It takes about 1 week after conception for beta HCG to become detectable in the blood and 2 weeks for it to become detectable in urine. If it has not been 2 weeks since your missed period, your home pregnancy test may be falsely negative.

Varies: Pregnancy tests will be positive depending on how sensitive they are to the HCG hormone. Implantation occurs seven to nine days after fertilization. Hcg hormone starts to be produced and can be measured a few days after implantation.

Urine pregnancy test - would it show a result if you're pregnant 29-32 hours after intercourse?

No: No, your pregnancy test would not show up this early. The pregnancy test only turns positive after a few weeks of being pregnant. If you're concerned about being pregnant and do not want to be pregnant i like you need to see a doctor to be prescribed plan b.

A 24-year-old female asked:

Is it true that if your pregnant in your tube or having ectopic it won't show up on a home urine pregnancy test? Should i just go to the doctor?

Not true: An ectopic will still show a positive home preg test. If you have risk factors (prior ectopic, tubal surgery, pelvic surgery, infections, endometriosis or anything that scars tubes) you should see your doc asap with a positive test. If your test is negative but you still have symptoms of pregnancy & one-sided pain with spotting; see your doc asap. Good luck & take care.
