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.

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. ...Read more
