When can the urine pregnancy test detect pregnancy? (ie, how long after intercourse)?

Answer 1

the day you miss your period and anytime after your late. they claim to detect before but dont

Answer 2

Home pregnancy tests are sensitive enough that they can detect a pregnancy as early as one week after fertilization. Update, June 2006, many home pregnancy kits are now more reliable and may be accurate as early as several days after a missed period. (If you usually have a regular cycle).

Home pregnancy tests are most accurate about 27 days after conception. This is when a menstrual period is 10 -12 days late, although some tests do say they can be used as early as 2 days after a missed period. * Update: Some of the new pregnancy tests say you can use them one day after a missed period. If your cycle is not regular, wait another day to use it. (Or you might be wasting your money).

Collect a good urine specimen. If the directions call for the use of a container, use a new or clean one. A washed-out bottle may interfere with the results. Most tests today provide a small disposable cup for you to use or you pee directly onto them. Perform the test in the morning when urine is the most concentrated. BUT, you can use them at any time of the day. (Refrain from the use of aspirin or marijuana the day before and the day of the test).

Results can be one of two things:
Positive. Almost always means pregnant. False positives (says pregnant when not) are very rare. Things that cause a false positive include marijuana, aspirin, hormones, birth control pills, methadone, tranquilizers, and soap or protein in urine.
Negative. Usually means not pregnant. False negatives (says not pregnant when pregnant) are fairly common. This happens if it is too early in the pregnancy to make the results of the home test accurate. If you suspect you are pregnant even though a home pregnancy test is negative, you should have a pelvic exam by a GYN health care provider and blood test or repeat the urine test in a couple days.

Remember, you can be pregnant and have no symptoms at all, except missing you period. If you have had sex without using birth control and are worried you might be pregnant, talk with a health care provider or with a counselor at your clinic.

How The Test Works (FYI)

There are many hormones in a woman's body. One hormone called HCG, (human gonadotropic hormone) is in her body ONLY when she is pregnant. Urine pregnancy tests are designed to react with this hormone (HCG), which is secreted into a pregnant woman's blood and urine by the developing placenta.

You must take the test at the earliest a day late of a missed period but the best is to book an appointment the doctor will do the best test when it is time most women don't find out until a missed period however you may have some spotting do to pregnancy and think it is your period that is why the doc is your best bet. good luck.

Answer 4

2 weeks is the absolute earliest any urine test can detect pregnancy. Many over the counter tests are not reliable that early. If you want a reliable test, you should wait until after you expect your period to begin.

Answer 5

If you are worried about unintended pregnancy you can take the Morning After Pill up to 72 hours (100 actually, but the effectivness decreases) after unprotected sex. If you can't afford the morning after pill, you can take some types of birth control pills in large quantities to prevent pregnancy. Don't try this until you first know wether or not your specific pill is effective in this aspect, though.

Answer 6

After the first day of missed period( sometimes earlier depending on the test) I would wait till then so you do not have to go through the false neg. I think that it is around 14 days after you ovulate or 28-30 days after your last period.

Answer 7

about 2 weeks

Answer 8

Up to 5 days before your missed period (First Response).
