Is a urine pregnancy test accurate two weeks after sex?

Is a urine pregnancy test accurate two weeks after sex?

If positive: You should do the test after a missed period. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex.

If I don't take a break for a week on the pill and run two packs in a row would a pregnancy test still have accurate results if I wanted to be sure?

Yes: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.

I had sex two weeks ago, my period is due in two more days. Can I take a urine pregnancy test now? And will it be accurate?

I had sex two weeks ago, my period is due in two more days. Can I take a urine pregnancy test now? And will it be accurate?

Patience: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.

Quantitive blood pregnancy test came back negative two weeks after missed period. How accurate is it? Should I still be worried about pregnancy?

Very accurate: The home urine pregnancy tests are also very accurate at 2 weeks after an expected period. Negative means not pregnant as of 2-3 weeks ago, but probably means not pregnant as of 1.5-2 weeks ago with these sensitive tests. So, if still having sex over the past 1.5-2 weeks, there is a chance of a brand new conception that is too early to cause a positive test result.
